No you can't, the public test realm is only to test the 'prepatches' such as talents, shared mounts. ETC.
If you wanna go to pandaria u must go to the beta.
to play in pandaria: a level 85 character, a Mists of pandaria license, and a wow account
World of Warcraft: Yes, you can change to other realms and create characters to play without losing the characters on your other realms. Just remember, there is currently a 50 characters per account limit to each account, and only 10 (11 when Mist of Pandaria releases) characters per realm.
To download WOW MOP you must have a WOW account and the expansion purchased. After that all you do is login to Battle.net, go to account page, select your account, then click install wow client on the right plane.
Sometimes WoW realms/servers are down for maintenance. Best thing to do is wait or go on the WoW forums and read about the server status.
As a part of the transition from Mists of Pandaria to Warlords of Draenor, we'll be making some changes to the Legendary Cloak quest line.
The Public Test Realm is closed for now. There is no new patch to work/test on. I don't know when it will be back but hopefully soon.
A quick search of the WoW Armory reveals that there are currently (as of JUl 26, 2011) 55 characters on the US realms and 36 on the EU realms with the name of Heavenscream ranging from level 1-85.
There are many, one of my fav realms is Funserver.cc
High possibility nothing needs to be "fixed." You have probably been logging in while WoW is under matinance and the realms list won't show up....Just wait for them to be done and your list will show back up.
No, there is not a "Murloc Server". Nor are any of the servers named after a murloc. All realms are exactly the same with the exception of the PVP flag on the pvp realms.
Currently there are 3 guilds on the European realms witht he name Anveena. Those realms are: Bloodscalp, Dun Morogh, and Ysondre. There are currently no North American realms with a guild named Aveena.
Really your asking what test your taking online wow just wow!!
