1. My most important rule is credit! monkeysbananas @ ij or something else similar will work. As long as you credit so that someone else would be able to find their way here it is fine. If I find you use my icons without crediting, I will be sad :_( and I will bug you about it.
2. Second, is please comment. I like getting feedback. It's always nice to hear that someone likes your graphics or wants to use them. I also like to know who is using them, so please leave a comment if you're taking any.
3. You may request graphics. In order to do that, leave a comment here or on any other post and I will get back to you soon.
4. If you'd like to be an affiliate, leave a comment on any post and I will put you up on the user info.
