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

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 $0 this month for my coding efforts.
I’m setting up a WP blog for a client that should enable employees to post a question to fellow employees across multiple offices. It is of limited value if the one who asks the question (author) is not notified when an answer (comment) is offered.
This seems like such a great solution . . . if I can get it to work!
Any suggestions?
Steve
Steve,
This may not apply, but if the blog you are creating is hosted on an internal network (ie outside people cannot get to it/mess with it) you may consider going with an older version of wordpress, as well as whichever version of Subscribe to Comments that works fully with that.
I’m hoping things get worked out, i want to use this plugin on my stuff at ponderplace.com.

Hi there - just downloaded the plugin after recently updatind to WP 2.3.1. Check box appears fine - only problem is it’s not sending out emails. I tried the ‘Is it working?’ advice on the plugin download page and…nothing. Any advice?

Quiero ver que tan bueno es este plugin..gracias
I have two blogs up, Wordpress 2.3, and I tried to install the Subscribe to Comments on both. One site works well, other 404’s me. The second site had errors posted to the dashboard when I activated the plugin, but when I refreshed the screen the errors were gone.
Q: How do I get back to pre-StC state? I tried simply deactivate-reupload-reactivate, but that doesn’t work, I still get the same issue. Seems it’s put something in mySQL or someplace else that I need to purge.
A nice plugin! I’d like to use it everywhere…
Mitch
Thank you very much.
Regards.
Thankiossi
It’s great
I just installed the plugin on my blog. That was easy. I would now like to move the checkbox above the submit button, like you have here. Do you have simple step-by-step instructions? This stuff makes me nervous!
Thankiosst
Great!
Thankiossk
Cool!
I am very happy with this plugin, except for one little glitch in this newest version (2.1.1). The option to remove the CSS clear doesn’t quite work. I unselect the option and click the update button. When I view the comment form it hasn’t changed, and when I return to the Subscribe to Comments options the CSS clear checkbox is still selected.
“I am very happy with this plugin.”
Estoy muy contento con este plugin
Muchas gracias por todo.
Saludos.
Hi Mark,
Any ideas why your plugin is not working?
When i’m trying to call wp_mail() function manually - everythig is OK, but it seems to be that send_mail() func in plugin is not getting called. I tried to put some debug code in there - it is not working. Some how it foes not go into send_mail function. Is it possible to debug problem somehow? I am not a php programmer.
Hey TF,
How would I go about cleaning out the names of those who have subscribed. I have a bunch of bot sign ups and want to get rid of them.
Thanks BD

Andrew: it does not work because there is a bug in version 2.1.1.
