Hi! I'd love to join. I've seen some of your icons on a friend's journal.

Randomly curious, since I can't see the icons to tell. Are you using some sort of image hosting service, or do you have more like a web hosting account? If the latter, you should be able to use an .htacess file to limit what domains/subdomains your images appear on. You'd think image hosting services would have something similar (I'm sure it would be a popular feature!), but I don't know enough about them to know if any do. I use .htaccess for my stuff because hotlinking sucks.
