Hey,
I've heard good things on Invision board and PHPP boards.
I was wondering, which would be the easiest to use and admin for a total non-technical Newbie like myself.

Also, I need one that is efficient, b/c I have limited bandwidth.

Can anyone estimate how many users/daily posts a GB/Month would allow?

Thanks!!

phpbb is the way to go

heh i suppose if you want to save money phpbb is the way to go but the defacto standard in quality forum software is vbulletin

yeah, vbulletin is very nice

vBulletin is definitely the one to go for if you have the capital, if not phpBB2 and InvisionBoard are great free alternatives :) As for bandwidth I operate a phpBB2 site which has around 10,000 posts and 171 users. It was started on 27th May and gets about 130 posts per day and it pushes 4GB a month. I actually moved the board from using InvisionBoard to phpBB2 because I feel it has much better moderation tools, the board will be getting moved to vB in the near future :)
