+1 for prints! And if you can't find a good-enough service... at least let us pay for higher-res image downloads. I just downloaded one of my images (1125x917px). I'm sure I could come up with a design where I'd pay for a higher-res version!

EDIT: Also, add a mailing list. I'd like to be notified when you get around to doing high-res or prints. Right now, I can't even find contact information to get in touch with you to make this request.
