There currently are no limitations to the classifieds other than needing to be a subscriber. It's possible to have a lurker that has not posted but wants to sell something, or a person who wants to subscribe only to list a few items. In the past driveby ad posters got away with free ads, now they have to subscribe. If this is getting abused I can look into it further but it gets tricky. If you say "you must be a subscriber and have 50posts to list an ad, then you'll probably end up with people posting nonsense until they hit 50posts, etc. As always buyer beware and try to know and learn who you are dealing with, similar to ebay. Things will be much better in june when the revamp of the site goes in and you can obtain more details of the sellers rather than having to dig around the site..
