Hey,
You can Bug with the Mount Bug under the auctionshouse at sw, and still use it + get your post, and the best - no one will ever see you.
For guys that do auctionshouse botting etc. this is pretty nice..because no stupid peoples see you stand there for hours & report you.


Makro to use the Auctionshouse ->
Code:
/tar Auction (english client)
/tar Auktionator (german client)
If you have the Auctions-NPC in target, press the interact with target button - the auctionshouse gui open & you can use the Auctionshouse.
If you want to get your Mails , walk 1-2 meters and rightclick the mailbox trough the Wall - it still works.
Hope the trick will helps a little bit at Auctionshouse Botting
