Thank Me Later is a plug-in which will automatically send a thank you email to readers after they post a comment. It can be set to send the message a time after the comment was posted (an hour, day, week, month, etc). It is effective as it will remind readers of their comments and gets them engaged with future discussion and your blog. It is useful to attract “one-time” readers who will post one comment, and then forget about your blog.

Thank You messages are fully customizable and provide use of “tags” which represent variables. So, for example, you can refer to readers by their names, and reference other variables including comment page, the comment ID, etc. Support for PHP is also included to make the system even more extensible to those with experience.

Version 1.0

Version 1.1 fixes a bug which prevents Thank Me Later sending emails. It is recommended you update to 1.1 as soon as possible. Also new in 1.1:

• Thank Me Later should now work when in a sub-directory of /wp-content/plugins/. This error was due to misuse of PHP’s basename function.
• Change in how settings are saved for performance reasons.

Version 1.2:

• Ability to send email for previous comments (for first-time use).
• Facility to send an example email so you can see what it looks like.

Version 1.3:

• Support for HTML emails.
• More friendly time settings.
• Send history, and scheduled emails.

Version 1.3.1 is a minor upgrade which supports localization, to allow for translation.

• Change in database table design, to support improved functionality. WARNING: By upgrading, all previous records will be deleted. This includes send history and comments in the queue.
