I just got mine from leveling a new toon on Kil'jaedon in the guild Stage Clear. (There was a post in the wow forums.) They have been doing this since November I believe. It's a pvp realm, however I had no issues with ganking. I made a goblin so I could get another goblin crawler pet to have to sale. I quested thru the goblin area, then on to the Ghostlands and briefly quested in Tauren Mill. I was lvl 26 at exalted (and make sure to buy the renown guild tabard once you get out of goblin land). You only stay in the guild until you get exalted and buy the pet ...and then they ask that you leave the guild. I'm very shocked that they do this nice gesture for we pet collectors.. gives me renewed hope in hard core raiding guilds.
P.S. Just /who Stage Clear once you make a toon and find an officer to speak with to get an invite. Don't know how long they will keep this up.. so I would act soon.
