The idea for HDGaming sounds good. There is a lot of buzz around High Definition at the moment and with the release of PS3 in a few months, there’s bound to be more.
In my experience, a forum site is pretty easy to set up. You just need to buy the software, Vbulletin is a good one, then buy hosting from one of the many companies around, upload and set up and you're off!
Good luck with any projects you decide to take on
