I found the Logo Creation Wiki as a good place to stretch my meager artistic abilities and keep up my Photoshop skills. I generally only create logos and favicons, but mostly just logos. I find making skins/themes frustrating, so I haven't done many yet, but I have done some changes for other wikis like Castle Age Wiki, the WoW Answers Wiki, and WoWRP.
This user uses Photoshop CS4 to create their logos.
