Feedback Issues

Not really an audio issue, but there isn't a better option! Anyway, I'm trying to leave feedback for a buyer, but the comments window is pre-filled with a former comment about him as a seller, and I can't delete it and add my own comments. Any suggestions?
Why don't you use the help option and email your question to Audiogon?
I did and got no response. The problem has since been solved: he hadn't marked it as "sold" yet!
