It came from this thread in the Tandy forums:
50 may be a stretch but you certainly have avalid point.I really think we need to prohibit brand new members from posting in the marketplace until a reasonable level of messages is achieve.. Like 50 messages. The number is arbitrary. Does anyone else feel a new member posting immediately to the marketplace rather than an introduction or standard thread is a bit off putting? I dunno I could be alone in this. Just thought it would lessen the spamming an illegitimate posts.
