I think there should be a post new thread button for you in the sale/want forum now. Someone else was having a problem with that recently so maybe there's an issue at the moment?
I think @johnny deals with subs.
no worries ill leave it up, but wanted ads are no cost, the other topics are a £5 to post a bus ad ( 2 weeks posting new ads) and £2 for parts for a weeks new ad posting) so its not per ad but on a week basis which i think is better value for money, its not much and it helps keep us afloat...
