Posts and replies in the classifieds section are not counted towards one's post count as the classified ads aren't archived. For this reason, along with the fact that we have a lot of lurkers here, often times you will see an item listed by someone who has zero posts under their name. The more astute forum members will look at your join or member since date, but others may not and it could affect whether or not someone will be willing to take a chance to do a transaction with you.

For this reason, I highly recommend you make a few posts - either a new thread or merely repling to others - in the other areas of the site so that you're less of an unknown to everyone when you list something for sale.
