Be nice to nOobs

I'm fairly new to good audio, and very new to Audiogon. What a great site! I looked at all the goodies, and thought, "This is a great way to try different stuff, sell it if I don't like it, and really listen to a wide range of gear until I decide what I like."

My problem is this: I've made several offers at full price, but in most cases never even received a reply. Is this normal, or is it maybe because I don't have a track record at A-gon? I've sent follow-up e-mails asking if the stuff is still available . . . and again gotten no answer.

I welcome any advice on what I'm doing wrong or could do better. I'm a noOb, but I'm a serious buyer, and getting tired of feeling "like chopped livah".

Regards,
David
