Dear Moderators,
I think sellers must be monitored on "how" they sell their stuffs especially in the musician's classifieds. Some of them starts a new thread like " FS: Guitar 7k"
upon entering you'll see only their cellphone number or "pm me" without any details on the stuff they're selling. They must at least give details and at least post a pic of their stuff or in the absence of a pic, they should notify the members on future update of their thread.
