I think that maybe the site would benefit from a Runescape category. Even though it's not really taken seriously by most, I think that a large portion of MMO gamers have started their careers playing Runescape through middle/high school. It's still pretty active as far as I know.
That is a good idea Runescape has a large community so it could possibly attract more people to the site!
I was pretty damn shocked to see that Runescape wasn't already on the forums. That is one of the biggest MMOs out there. It would drive massive traffic to the site.
