If your guild is tired of its server or name, you'll definitely want to read Blizzard's latest announcement. Community Manager Netahera just posted on the official forums that Blizzard plans to implement both a guild relocation service and a guild name change service in the future.
Check out the announcement after the jump for all the details. You can discuss the topic in this thread in our World of Warcraft general furm.
Guild Transfers & Guild Rename Services Coming
We want to give everyone an early heads-up regarding our plan to implement a guild relocation service for World of Warcraft. The idea is for a guild leader to be able to transfer a guild to another realm. The guild structure remains intact, including the guild leader, guild bank, ranks, and guild name (depending on availability).
Guild members who decide to relocate with their guild may initiate their own paid character transfer. Upon a successful transfer they will automatically be part of the guild when they first log into the new realm. Their guild rank and guild reputation will be intact.
Guild leaders who do not want a change of scenery may also choose to pick a new guild name using another new service. These services are in development and we will be providing additional details at a future point in time.
As with all of the features and services we offer, we intend to incorporate the guild relocation service in a way that will not disrupt the game play experience. Please note that this feature will require extensive internal testing, so you may see bits and pieces of the service appear on the public test realms. We'll announce further details at http://www.WorldofWarcraft.com.
