The global forum Plugin allows you to create sitewide forums(as you see in bbpress) which are not linked to any group. It works just like standalone forum with the exception of a few things(like template/plugins). Thanks to @Greg for bringing the idea of global forum in buddydev forum and here we have it.
- Standalone sitewide forums
- Allows you to create subforums
- Support for category forum*
- Fully templatable
- templatable admin section for forum management
- Full tag support(add tag/delete tag)
- And most of the thing which you expect from bbpress is available.
