Paid forum owners-- please help

Tweet

I've been thinking of running my own paid forum or gpt site-- or maybe a combination of the two. I'd like to start off with a forum if possible, because it seems the most easiest to start right now. I know that shiftcode runs most of the gpt/offer sites. What places are forum servers, or places that I can look into to see what packages they have? I've done a google search, but it's not bringing up what I'd like to see.
