Bulletin board or forum requested

[eluser]Unknown[/eluser]
Hi gurus!

I have starting with new project with my favorite framework CI.

One part of my target is some king of bulletin board (or forum) for team players. I have no any special requrements. Somethink like this support forum is. Team players should communicate together in threads and coach will be let many kind of information messages for players.

Only requested issue is that it should be CI library without its own user management

I have try to find without results. Can you point somethink useful to me ... ?
