I've been having much too much fun with my icons. At first I felt very protective and parental and didn't want to let any of them go, but now that I have lots of them, I don't mind so much ... and it's very warm and fuzzy to see them show up in other folks' posts.
Samples:
If there's another one I use regularly that you'd like to have, you can always ask ... (the ones I still feel the most protective about are the Yukimura ones I use regularly), and I love making them by request too.
ETA: And I meant to put all the disclaimers: no hotlinking to my poor Earthlink account, please credit, etc. etc.
