Someone posted a link to a free php board like a month ago and now I kinda need this link but I can't find his post... I don,t even remember the name of the guy... If you're the guy who posted this, please pm me...
I sware I posted it, but I can make you a sub from my short domain(4 letters not including the .us) and can get you phpnuke,or phpbb for free. I can install it for 25 creds or you can install it yourself(ftp comes with sub).
Ya, there are tons out there, just google Free PhPBB and you can come up with TONS of them. I have found acouple from about 5 seconds of searching, and set one up awhile back. Google is your best friend.
