This plugin is for bbPress 2.x
Many people who run forums would like to know when a new topic (thread) has been posted but do not have the time to constantly check their forum for activity. This solves that!
This plugin will send an e-mail notification to specific addresses when a new topic has been posted. The users who receive notification along with a simple e-mail template is configured in the bbPress settings.

This plugin enables sending of a digests with a list of topics active on a bbPress-powered forum in the last 24 hours or 7 days.
Users are able to choose on their profile edit pages (both built-in and from bbPress) whether or not they want to receive digest, at what time of the day, at which day of the week (if they receive weekly digest), and should digest include topics from all forums or only selected ones.
It requires that cron runs regularly at least once an hour.
bbPress Digest is a very lightweight, it loads necessary files with functions only when needed.
If you are translator, you can translate it to your language and send translations to plugin’s author.
