Just a comment:
As a new user, I cannot post a reply to a "For Sale" ad until I have 15 posts. It seems to me that the new users are the ones who are most in need of answering those ads since most of us are first time Jeepers looking to ad to our new ride! Although I can PM the original poster, it'd be nice to be able to post the customary "PM Sent!" message or respond to an ad with a post ..
