I am a source mapper who is currently working on the horror mod Asylum (www.moddb.com/mods/asylum3) for Half-Life 2: Episode 2. I also write some music, edit videos of Sony Vegas and generally photograph things, including for stop-motion animation. As you can see, quite a bounty of random hobbies.
Are you a Level Designer? Are you looking for help/support or other level designers? Then this is the group for you! Doesn't matter what you map for...
