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.
