Forum software

I have often ran away from forum software as people generally don't use them, they never get updated on servers and leave holes for hackers the size of the grand canyon. Oh and ex-staff members write things and teenagers have their fun. But when wordpress releases opensource software for one, it makes me think it might be lighter and tighter. If 9Rules is using it, it must be alright! "Have you ever been frustrated with forum or bulletin board software that was slow, bloated, and always got your server hacked? bbPress is focused on web standards, ease of use, ease of integration, and speed. We’re focused on keeping things as small and light as possible while still allowing for great add on features through our extensive plugin system." Have a look at BBPress
