Personally, I think that if you want to set-up a xrealm gold trade, you should do so on the forums. That'll let you pick the person you trade with depending upon join date, activity, etc. And it'd give you a good ability to vent with if you get shenaniganized...
On the xrealm post... I think Xrealming should be as difficult as possible, while still enabling people to enjoy the game. Also, there must be a frightening amount of gold on the server for our population simply based on tali prices on order side. So this could actually hurt the overall economy in general.
