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”.
Download
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

I’ve spent a lot of time writing this code and supporting it. If you derive some benefit from this code, please consider showing your gratitute in a more tangible
way. Thanks!
I have received $30.00 this month for my coding efforts.
1. This site really needs Akismet!
2. Anyone tested this plugin on 2.5 yet?
Dear Mark,
I translated the .pot file to hungarian. Iwant to ask you how can I use this after the translation? I must to append this to the existing hungarian wordpress .po file, do it to .mo, and upload, or is an other way too? Upload as a separate file, upload with a definite name, etc.?
An other question: How can I see who subscribed to a special post? If I click to a title under the top subscribed posts, there is the post, not the list of the subscribers to this post. Can I see this an other way?
Thank you for your help!
Best Regards,
László Koloszár

Hi!
I’m seeing the following error on my admin screen, when approving a new comment in WP2.5 :
Catchable fatal error: Object of class stdClass could not be converted to string in /root/…/dd.com/wp-content/plugins/subscribe-to-comments/subscribe-to-comments.php on line 329
This is the line in question:
$this->post_subscriptions[$postid] = array_unique($this->post_subscriptions[$postid]);
Any idea?
Thank you!
Oliver
@Dan - you asked if this worked with WordPress 2.5? The answer is “Yep!” Works like a charm. I had no problems with it at all. To view a list of people subscribed, the UI is located under Manage > Subscriptions. To play around with how the subscription form looks, go to Settings (top right) > Subscribe To Comments.
Obviously this is AFTER you’ve installed and activated the plugin.
Speaking of… Mark, thank you SO much for such an easy to use and extremely useful plugin. Your hard work is very much appreciated.
one of the best plugins!!
Just a heads up, I love the functionality of this plugin, but I had to recode quite a bit of the html for some of the sites I’m going to be working on. Part of this being I wanted HTML instead of XHTML, but the other part was to be valid, and it should be a simple thing for you to fix: you’ve accidentally placed some of your fieldsets and legends on the outside of your form tag.
Most of this seems to be in the management section of the tag, for example line 1150 lists the fieldset tag, where 1157 has the form tag - fieldset and legend elements should be outside the form element for validation purposes.
Sorry for the bug post on the comments, I don’t have a WP developer account:). If you need my code, let me know, I’m happy to submit. Thank you!
