I think that having FS or WTB in the title is just common sense, and definitely agree that the moderators don't need any more babysitting tasks.
My "wants" for that forum are:
1) A requirement that the poster has an email address in their profile - this is something that could be automated.
2) A method for smacking people on the head when they include their email address or phone number in the post. This might take a bit more work...
