I've recently got my new site up and running, called LinuxGD.net. To put it straight, it's a community for Linux game developers. The site still needs a lot of work, but it's open for registrations.
Thanks to the power of Joomla the site has an awesome article system and forums have already been integrated. I'm planning on adding more community features like groups, etc., etc.
EDIT: Oh, and the logo needs a serious overhaul... 'twas a 5 minute quickie...
So head on over - http://linuxgd.net. And feel free to make any suggestions.
