Help! Drafting Error!

I'm sorry if this shot is a bit spammy, but I didn't know how else to get Dribbble's attention. About 20 days ago I invited Omar Aqil to open a Dribbble account so I could draft him. He wasn't a prospect before that, but I knew of his work and thought he'd love being on Dribbble. He signed up, but even though his page is tagged as "PROSPECT", I couldn't draft him. On his page, and seemingly only on his page, the "draft" button doesn't show up. I've tried contacting Dribbble, but I haven't heard back.

If anyone knows why this is, and/or how to solve it, please tell me. It's really not cool telling someone that you want to invite them to Dribbble and then let them down.
