For anyone interested, I have just started my own guild on Drak Tharon (US) server. We are a horde raiding guild. We are looking for any level 85 who is either already on our server or willing to transfer over to join our ranks and begin progressing through Firelands with us. We have a guild bank with multiple tabs and ventrilo set up for all of our members to use! We have a small website in the works as well for our guild.
And ya know, if you just wanna play on the server, we can offer any level a home. But we are really looking to fill out or core raiding group. Let me know!
