free php forum

Hey dudes, I figured I would get some valid opinions here.

I am looking for a forum to use on my site.

here are the rules

must be php
must be free
must use mysql
must allow styles and graphics to be changed

My purpose is to commicate and STORAGE of ideas with clients for web design. So basically a forum, but if traditional project management is blended, that would be perfect. I am searching freshmeat right now but I figured I would get some good reviews from you guys.

Thanks

also needs to allow me to edit the code to suit my needs.

what I really want is one forum per project so each user would have a login to one forum.

I have tried 2, one is great BUT it does not allow me to have dictate what user sees what forum.

anyone know anything which will let me do this, I could modify one, but I need it quickly to role out to clients.

Thanks

one of the best i've seen is YaBB

thanks for the pointer but I found a perfect one.

It is called phpcollab and is perfect for comminucating with clients and also remote team members. With ghreat project management control, easy to use and set up.

Well worth a look.
