MySpace is a Great Place to get Autographs.
But you need to know who is real and who is a poser.
I do my research. But here are a few that I have obtained from going through MySpace.
I am a fan of 80s music, so most of them are singers from the 80s.

When emailing them, to grab their attention, put "PLEASE ADVISE" as the subject line.
I find that always works!
