Thought it wasn’t starting until tomorrow (runs to stormwind). I’m not a pvper by any stretch but I want to be a (void) zombie. Now if only we could get the voidform suggested in the Void elves and void form thread.
edit - yep it’s auto flag, must remember to go to Icecrown via Dalaran and wait for the flag to drop off.
edit 1 - no zombies 
so I went back to icecrown. My name went back to blue as I got there but the pvp flag above my name stayed on countdown, hopping a flight to icecrown removed it though.
