Not sure if this was already posted, but ill post it anyways...
Always wanted to be like those floating mages above the IF AH? well now any class can get there.
All you have to do is either have a cool down on your hearthstone or destroy it and get one later. after that, you hop onto the barrels stacked up to the left of the auctioneer (the one that you first see when you walk into the AH)
and go to the Problems GM's can resolve tab, Stuck, and press auto-unstuck. MAKE SURE to be facing directly towards the platform.
After that, just go to the far back right corner (get as close to the edge as possible) and jump until you get to the top. Its pretty much like standing on top of an invisible box.
ill try to post screenies asap
