Eric, I think that one of the dynamics that is missing is the need to go somewhere else to see what is for sale. I would suggest allowing a posting in Want Ads that is titled Outdoorbidur where basic announcements can be made of for sale items with a link directly to the ODB site for all the details. This notifies folks of new for sale items and shares it with the whole forum then drives them to Outdoorbidur to do the transaction. This should keep the visibility of for sale items high and hopefully moves that activity over to the appropriate site. You will need to have a moderator oversee it to make sure they don't fall into the old habits but that's nothing new.
