For Sale Ads now Close 30 days after last posting.

I totally agree that something should be done about folks who neglect to mark their thread as "SOLD" once they have sold an item, is there any other way you could get the desired effect?? Like....no advertising for 30 days if you don't mark your ad as "sold". At least that way, the only person that would affected is the person(s) who is/are causing the problem.

Not without adding a lot of work and conflict for the moderators -- and then leading to accusations of favoritism because we missed something.
