I do agree that it sucks that there are people who show up, post a want ad, and then never talk on here.
I was mildly wondering if a threshold post count should be considered below which the buy and sell ads will not appear nor function for.
Lets say, you have to have 25 posts before you even see the ads. and you have to have say 50 before you can open a thread in the ads. ... Just a humble idea, no pressure, but I do think it might help build confidence.
