Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
I have been to the IRC channel for the PHPDN, but I would like to recommend another (no offense IRC people). There is a MASSIVE PHP channel at irc.quakenet.net , #php . I give this channel 5/5!
