And perhaps you'll want to make a separate thread for this question, but we know there is a timer on commerce xp, as in, I barter/sell an item, and then there is a timer that needs to run down before bartering/selling will earn me more xp. It would be nice to know how long one needs to wait before commerce activities will once again earn you xp. Commerce xp is one of the hardest to earn, in my opinion, aside from doing the automated quests that give it out.
