Do you or have you paid for forum software just to use a forum as a hobby and nothing more? I've personally never even paid for the forum software and always have used free software. I don't really see the need to blow money on something that's intended for a hobby only unless you're wealthy enough to afford it. I might not have all the nifty features in the world, but most free forum software offers you the essentials you need to run a (semi) successful message board.
