What happens if I create a new guild with the same name?
When I first rolled Horde on Feathermoon (RP server), I made a rogue named 'Dirtydeeds'. He lasted a whole 2 weeks before the powers that be changed his name. I got an email from Blizzard saying that name was innapropriate for a RP server.

I deleted him and remade using the same name. Never have had a problem with the name since.

As far as innapropriate name, I thought 'Dirtydeeds' was dead on for a rogue.
