WoW World of Warcraft Guilds
A guild is a group of people that play a game together (or several), they do quests, perform raids and chat together. In World of Warcraft you do not have to be a member of a guild if you do not want to but if you find a good one it will make the game experience much more fun.
The guilds interface in World of Warcraft works similar a friends system in an Instant Messenger and there’s also a private chat channel exclusive for the guilds members. The guilds leader can set different ranks/titles on the members of the guilds and promote those who do a good job.
