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

How or where can I customize the e-mail notification text?

very cool Plugin. I like to use it…
Hi Mark
thank’s a lot for the great plug-in. I have one issue with it I’d like to share: after having localised the language of the text next to the check box in the word press settings into german, the check-box is pre-opted in. De-installing and re-installing the plug-in did not change anything. I wouldn’t like to force a pre-opt in to my readers - is this a new bug, or do you have any idea how I can get back to not-pre-opt in?
Thanks a lot

Hi,
Anyway this could be “fixed” to work in “moderation mode”?
Currently if you subscribe to a post you are not added to the subscriber list until your comment has been approved.
Which means you can very easily miss a ton of comments if the blog administrator has not yet approved you comment and thus subscription status.
Thanks,
Will
Great plugin for Mizpah TV Magazine, this comments plugin does the job nicely.
Has anyone tried running “Subscribe to Comments” on WP 2.5.1?
I’ve uploaded subscribe-to-comments.php into the WP-Content/Plugins folder, and I’m able to activate it, but it does not appear in my list of selectable widgets.
Any idea what I’m doing wrong, or is this version of the widget just not compatible with WP 2.5.1?
Thanks
Oops! This is not a widget! Stupid me. OK, I found everything where it should be, but I’m still having some problems.
For the record, I’m trying to set up Subscribe To Comments v2.1.2 within WP2.5.1, but it doesn’t seem to be working right.
I followed the (simple) installation instructions, then ran the test in the readme file. Using some sample accounts that I created, I wrote a new post, submitted a comment, then replied to that comment.
However, problems occur when a “subscriber” attempts to select manage subscriptions, an error occurs stating that “You may not access this page without a valid key”. Also, Subscribe To Comments doesn’t seem to differentiate between a subscriber and an author. By that I mean that in my test, when the author looks at his own reply, the plugin should recognize him as the author - However, the plugin is reporting him as a subscriber.
Any idea about what’s going on?
Thanks
Has anyone got this plugin to work successfully with WP 2.5? I’m dying to install it.
It should be explain in the readme of the plugin. Lot of worries for the lack of a simple information. Thanks again.
This plugin sends emails to everyone, even if they don’t check the box to subscribe to the comment. Using Wordpress 2.3.3 (haven’t upgraded to 2.5 yet). Have to disable the plugin until it gets fixed…
Also can’t submit a ticket for the bugs… the link is bad
This plugin made discussions on my blog much more consistent. Thanks a lot!

Hi and thanks for the great plugin. I have a feature request, but am not allowed to create a ticket on the link you’ve given. So i’ll aks here. Like Oli i need to customize the text in my notification e-mails. First my readers are german. Second my readers often answer the notification e-mails they receive, rather then returning to the post and answering there. I need to give some hint that it doesn’t work - without mixing up the code of the plugin. So i think there should be some possibility in the options page to do so. greets, lev
