When I'm not blogging I like to waste spend my time on a few forums. I'm going to list them in no particular order.

Front Row Crew Forums - Home of the GeekNights podcast, the Front Row Crew forums are very active with a small group of users. Topics cover a wide spectrum of issues and debate always ensues!

Kenzer and Company Forums - Home of the Kenzer and Company games such as HackMaster and their wonderful magazine Knights of the Dinner Table. I used to admin for these guys but now I mostly just lurk on their forums.

Serebii Forums - Home of major Pokemon discussions! You didn't think I would leave off a forum that deals with Pokemon, did you?

Dharma Secrets Forum - A home for all sorts of discussions on the TV show Lost. This forum is chock-full of Lost goodness. However, you need to register because during peak traffic periods only registered users can use the board.

That's it. Feel free to check these boards out.
