Mythic has made it on the cluster server that you have to wait an hour to switch realms. In my case, this is not true. You just have to be logged in to one zone for an hour. After being in a zone (NF, any dungeon, etc) type /clientsleep backround. After typing this, press Alt+Ctrl+Delete. When doing this, go into processes and find game.dll. When you find this, click and end process.
After ending game.dll process, you will be able to log into any realm...enjoy!!
----Confirmation?...sounds very good.----
