We have talked about this many times before, and I wanted to share another tip for both people who are looking to spread the word about their skins, or just members who would like more customization topics to read about. I got a nice e-mail from a moderator at Reddit who has a sub-forum over there dedicated to desktop skinning.

If you are a member over there be sure to stop by and vote up some customization articles, or submit your own!
