I was just wondering...and I'm not sure if this is the right place to post this, but have any of you guys ever had problems with people paying you for art, but then disappearing completely and leaving you no way to contact them before you can even send them their picture? Like they fall off the face of the earth, do not answer your questions, do not reply to your notes/e.mails/IMs, making you wonder whether you should bother to finish the picture or not.
I'm not sure if it's something to be worried about, but I don't want to labeled as a "money stealer" later on in life when these people magically pop up again years later still expecting their picture. I've had this happen to me twice now, and it's kind of disconcerting. It plays with your head, you know?
