I for one say good addition to the site rules and set up. If you don't want to be part of the community here, there's always craigslist for buying and selling stuff.

Now if there was only way a for us to make a rule that says if you post something for sale, you also must be willing to respond to posts and PM's in a timely fashion.

I mean WTF, more then 24 hours and no response? If I post something for sale, which I've yet to do here but do lots of elsewhere, and someone asks a question or requests more info I'm Johnny on the spot with a response. (especially if someone says they want to buy my item)
