What is the best PHP Message Board?

i would have to go with PHPBB.

btw. Pejone, i dont think vBulletin is free
It looks very good,
what do you need exactly??
If you want we can try to make a secure login system with cookies and sessions.
Never done that, but could be fun!
Open a new post in the php general forum.
