Where to find CI forum

Seeing as CodeIgniter has no standard user management/authentication system, you cannot simply plug a forum into it. It's impossible, and many have tried.

There are several half-finished forum systems around with their own user system that can be found via our mutual friend Google, but there is no quick solution to this. I'm surprised your forum search didn't find several posts saying the same thing, as I have answered this request many times myself.
