The big shocker here is this:
Officially sanctioned gold selling in Diablo III, people doing it just have to pay a BlizzTax on...
If so, which server? PVP or PVE?
I've copied Raegenheri over to Lich King (PVP) and am downloading the client now. I'll check out Northrend, but after I've made a Gnome DK :)
