setting up a forum is a lot of work and if you check the auto poster kurt mentioned in one of the threads there are plenty -

11k express engine - 28k phpbb - etc -

there are over 200 webmaster boards and most of them are flooded by hired guns (signature link spammers) and if you dont watch the board then it will be overrun by xrumer spammers too LOL

the information exchanged on those boards is worthless..a lot of boards are now giving out prices/points to members to keep them...etc

but in reality there is nothing better than user generated content...
