Not really a showcase yet as I've decided to run the 1.1 beta, but just wanted to put my URL out there in case anyone is interested. Once 1.1 hits gold, I plan on having a skin done. Basically the forum is focused around social gaming -- be it the social games like you may play on Facebook, MMORPGs or console/PC multiplayer games.
I'm a lifetime, multiple license vBer (since 1.0) and this is my first run with XF. So if you can offer any hints, tips or suggestions, that would be great.
