Topic: NSGN: Christian community
I'm on the "staff" of NSGN, a small Christian forum who's name stands for Now Spreading Good News. A few days ago we switched from phpBB to PunBB, in the hopes that we'll get less bot spam. I personally think we need additional defenses, but the site owner has decided to take the wait and see approach.
I recommended PunBB to the site owner because of the simplicity, standards compliance, use of pure CSS (no HTML or PHP) for the themes, and speed. I found out about it because I used to frequent the MacAddict Forums (now called Mac|Life). It's good stuff, and is working well for us.
