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

Installed! good stuff!
I was wondering what some of the more mature members here do about dating. It seems much harder for older singles to find a mate, so I might be turning to online dating for older singles.
any suggestions? thanks.

Installed the plugin but the subscribe section does not appear at the bottom of my comments fields. Does it tie in to some code somewhere in ‘theloop? Thanks.
That is cool.
Is it possible with this plugin to sign up a user to receive all comments on the weblog by default, not just to receive the follow-up comments of a post in which they are interested?
No, but that would be really cool.
thanks, I am going to try it out.
keep the good working,
ok, now how do i unsubscribe from this? i am getting notified everytime now and my question was not answered….
Subscribe to Comments 2.1.1 Does work with Wordpress 2.3 however there are a few issues i’m experiencing.
My setup.
Windows 2003 server
IIS 6
PHP 5.2.3 (using ISAPI extensions)
MySQL 5.0.37
on
Wordpress 2.3.1
Mistylook 3.5 theme
And using a bunch of different plugins.
::ISSUES::
Users who are not logged in receive an error “You may not access this page without a valid key.” When they attempt to manage their subscription.
The issue is not present when logged into admin console.
Hi!
I try to test “Subscribe to comments” in my blog without success. My version of WP is 2.2.3, I think that it’s compatible with “Subscribe to comments 2.1″, or not?
In fact I don’t receive the emails when I test… I don’t understand, I followed the instructions: I am disconnect from my table of administrator, I left a comment with an email different from the administrator’s and from the article’s author, and finally I left another comment with another email… And I do not receive the famous mail… I also looked at the configuration of the plugin, and it’s well configured, with all the fields filled correctly…
Does somebody have any idea of which can be the problem? Did nobody have the same concern?
Thank you by advance.
great site, this is what i am looking for
After many researchs and a lot of tests… I’ve found the solution!!!
For the future, and if somebody have the same problem… the solution is that:
In fact, the problem lay in the configuration of “$phpmailer” necessary for my server, and I’ve finally modified the file “pluggable.php” (sorry WP french version, I don’t know if it’s the same file in others languages) by respecting his configuration.
Bye!!
Hi Melinka,
Would appreciate it if you could outline the steps to modify the configuration of “$phpmailer†necessary for your server, and the file “pluggable.php�
Thanks!

Good and really useful post for all readers and specially for me, thanks!

Blessings and Peace:
I’ve installed the Subscribe plug-in, and added , right after in the file comment.php
I’m using the plugin in conjunction with a CommentPress theme. One of the immediate effects that I encounter, is that the plugin is REQUIRING that a commenter be ‘logged in’ before they can comment.
This is not my desired outcome. While I want to allow commenters to follow a thread, I do NOT want to mandate that they create a login account.
Can someone please advise, as to how this can be negotiated.
In Service of THE ONENESS,

Addendumn:
The challenge is, as I look further through the WP files,
that there are several files with in them.
WHICH is the exact file, to insert the code for showing a manual subscription form (check box)?
