Sorry Alan, I'm going against the grain here but I think you're being harsh.
He has clearly signed up well over a year ago, and has been using the forum. Just because he hasn't posted, he isn't allowed to post an advert for his car? If you go through the member list, there will be a huge number of people who have never posted, because they know how to use the search function, so always find what they want. This is something that is encouraged, yet when he wants to actually post something, it's not allowed.
