Although I understand the intent of the classifieds section taking things straight to PM's, at times the feature of our good old 'for sale' forum that lets people post to the thread is nice too. Lets people discuss an item and make adjustments in a discussion format beyond a simple ad.
I can understand though that this might detract from the technical orientation of the site though.
I'm just throwing that out there to make your life difficult during the revamp Mike.
