Left a note in the classifieds regarding your ad for Roberts gear but I wanted to add to that. 1) You are responsible for your ads in the classifieds. This includes communication, shipping, updates to the ad to indicate when items are sold, etc. 2) By posting it for Robert you have removed the sites PM system from the options to assist with communication. You've also limited the sites visitors from being able to search for Roberts past transactions to ensure he's on the up and up. That isn't good. 3) Don't post ads with a subject title of "UPPER CASE". It's not needed and bad form.
At this point you are on the hook for communication updates. I suggest you delete / close the ad and have Robert post it himself.
