New pvp server idea: Guild Wars

[Baler]

Everyone is placed in the same starting guild upon character creation.
Players can still create a new guild and have other players join however they will be able to pvp all other players not in the guild.
People within the same guild will appear blue to each other.

This way players can create their own 'teams'.
Newbs will have their global 'newb guild' chat.
Guilds can fight over spawns/mobs.
Solves the problem of AEing your own guild members.
