__________________________________________________ ____
o Player Uploads head via head uploader page.
o Other players download that head using ToriUpdate.
o Player decides to switch his head, and uploads a NEW one, with their same username, using the upload page again.
o
__________________________________________________ ____

What happens then? Are you stuck with that head until the other users delete it or what? Sorry to bother but I was just wondering this. . .
