Subscribe to Comments 2.1
Subscribe to Comments 2.1 is a plugin that allows commenters on your blog to check a box before commenting and get e-mail notification of further comments. It is one of the most popular WordPress plugins out there for the simple reason that it helps foster a community around your blog by encouraging commenters to come back and stay engaged in the dialog.
Features
- Rudimentary security
- Users cannot enter a random e-mail into the subscription manager and modify someone else’s subscriptions
- In order to modify subscriptions, users need to use a special link, given in notification e-mails, and printed in the comments form as long as they have their comment cookie
- Recognition of subscription status
- Unsubscribed users see the “subscribe to comments” checkbox, but subscribed users see a “Manage your subscriptions” link
- The author of the post is recognized by either login or comment cookie and is assumed to be subscribed to the entry (as they will receive notifications through WordPress)
- Themeable subscription manager
- Uses visual style of WordPress interface
- Can be optionally accessed via “Manage” menu in WordPress
- E-mail verification of block requests
- Javascript “invert selection” link to check/uncheck subscriptions for mass deletion
- “Return to the page you were viewing” link that persists at the top of the page, so that users can easily return to the post they were reading once they are done modifying subscriptions
- Ability to let users change notification e-mail address
- In the subscription manager, users can request that their notification address be changed for all their subscriptions
- Special link is sent to the old address for verification
- Once clicked, their e-mail address will be changed instantly for all their comments
- Easy integration into comments form
- No modification of comments form needed for WP 1.5+ (supported themes)
- For users who want custom placement of the checkbox/link to subscription manager, this can be done with one simple function call, placed anywhere in the comment form
- Subscription without leaving a comment
- By popular demand, you can now offer visitors the option of subscribing to comments on an entry without having to leave a comment themselves
- If the reader later decides to join the conversation, their subscription continues without them having to explicitly set it
- Customization
- You can make the Subscription Manager that your users see use your theme’s header, footer and sidebar, using CSS to style it to fit your site
- Internationalization
- I’ve written Subscribe to Comments 2.1 with i18n in mind, making full use of
__()and_e()functions. The domain is “subscribe-to-comments”.

Version 2.1 Update
Version 2.1 of Subscribe to Comments has a feature that people have been begging me to implement for many months: you can view the list of people who are subscribed to posts on your blog, and you can also see a list of the most “subscribed” posts. Also in this version is a new one-file install. You just put subscribe-to-comments.php in your /plugins/ directory, activate, and you’re done. This version will work on WordPress versions from 2.0.6 through 2.3.1 (highest tested).
Versions
- 2.1.2 Fixed a few bugs that’d send bad notifications (thanks Donncha!), cleaned up some code and moved to using proper WP escaping functions
- 2.1.1 WordPress 2.2 compatibility! Also note that support for
attribute_escape()is needed, so if you get errors about that, upgrade to the latest version in your branch - 2.1 big update, fixing a few potential XSS holes, and misc error messages… see above for details
- 2.0.8 XSS security fixes, hopefully fixed “+” symbols in e-mail for good
- 2.0.7 additional “funky e-mail” fixes
- 2.0.6 support for e-mail addresses with “+” symbols, option to disable CSS “clearing”
- 2.0.4 potential security bugs, better WP 2.0 capabilities compat

@Blog’s Magic — this question keeps on coming up over and over and over.
So I keep posting this link over and over and over.

Last night I think this plugin brought down my whole site. I had been using it successfully for about a week but when I turned Wp-Cache back on due to a large Stumble traffic burst the site went down with an error saying “The mail cannot be sent” right after I approved some subscribed comments.
Do you have any idea why this would happen? Have you seen it before?
Thanks.

I changed the way your plugin loads the text_domain. Now all strings are translated even if a user copies your plugin in its own subdirectory together with the mo-file.
In line 807 change it to:
load_plugin_textdomain( ’subscribe-to-comments’,'wp-content/plugins/’ . dirname(plugin_basename(__FILE__)) );
(I could also mail you my changes. Just write me a mail)

thnk you very muchh
Really nice plugin thank you very much
Even with the CSS clear (un)checked, the label text next to the subscribe button seems to be missing or white(?). The plugin itself seems to be working fine (I get notifications). Just that I can only see the checkbox and not the check box label. Any ideas? Theme conflict?

continued…looking further, in the plugin admin page, none of the fields below the two check boxes are filled in. This is the case in the majority of the themes I try.
Is there a way to manually implement the code (tag?) vs. plugin?
-gb
Great, hopefully this will help get people making comments to come back and respond to others comments!
This worked great… thanks.
Looking forward to checking this out.
Hello,
where can i translate the text into German ? Directly in the php-file via the plugin-editor ?
Great plugin…!
Cheers

Works great, but how can I change the email that is sent to list something else other than the title of the website in the “from” field and “subject” field of the email.
Preferably, I would like the from to be “No Reply” and the Subject to not include anything other than the “New Comment On: title of post”
thanks
Translations / what to do with mo-file? / How does it work?
Great plug-in. But I need to translate it. I started translating the pot-File with the poEditor. I generated the mo-File. But what than? I transferred the file into the /plugins/subscribe-to-comments-directory and tried it with several different names, like subscribe-to-comments-de_DE.mo. But nothing happens, still all in English.
What I am doing wrong?
Thanks - gl
Well, I got it by my own and even do have a brand-new German translation file. If someone would like to get it: public@LeniDesign.de
Hi,
I’m sorry but I have the latest version of Wordpress, the latest version of your incredible plugin, and only one problem left : the translation .pot doesn’t work. I’m not the only one. No one can succed to make it works (see http://www.wordpress-fr.net/support/sujet-848-resolu-subscribe-comments). Have you an advise (different from buying a brain :-)) ? 1000 thanks in advance.
Hello

G’night
Here is the bulgarian translation of this wonderfull plugin: http://www.darganov.com/wp-content/uploads/2007/09/subscribe-to-comments-bg_bg.zip
If found a bug in this plugin. It is related to the path of the translation files, the plugin searches for translation files only in the /plugins/ folder and not in the folder of the plugin even if the plugin itself is in a subfolder. So, you should put your translation files directly in /plugins/ folder in order to worke.
Hi Noname,
the German pot is corrupted, too. What I have done is, I read the file with the Web-Browser Amaya - it was the only one which showed the html-code correct. This is by the way the problem. The pot-file is html-code.
After the browser displays the content correctly, I copied just the text to a text-file and opened it with poEdit. Some changes have to be done here and there, but than it works.
cheers - gl
Hi Marcelo (#2355)
I assume the mo-file is created successfully. Than name it subscribe-to-comments-pt_PT.mo and copy it together with subscribe-to-comments.php directly in the plugin-directory of WP, not in a sub-directory.
“pt-PT” probably must be changed to what you have inserted in the WP-Configuration-file.
Hope this helps - gl
Great ! Thanks all but thanks Gerhard in particular because you have solve my problem ! It should be explain in the readme of the plugin. Lot of worries for the lack of a simple information. Thanks again.
Thanks..

Hi,
It’s me again. I have a new (perhaps old) problem. I have tried to subscribe to comments on a post, and when I add comments after my subscription, I receive no email, never. So the plugin doesn’t work… I ignore if it’s due to the .pot (whitch works greatly now). I don’t think because the plugin doesn’t work whithout the translation either… Why it’s fall on me, it’s my sad question. You can see the site here : http://www.jaideuxamours.fr
Thanks for any help.
