GuildMateMap displays your fellow guild mates on the world, continent, zone, and mini-map inside the World of Warcraft. Each guild mate that has GuildMateMap installed will display their position, current level, class, and guild rank. So, when you are in gankville, one quick look at your map can help you call in nearby re-enforcements.

Left clicking on a guildmate in the world map will start a whisper to that person, and a right click invites them to your group.
Left clicking on a guildmate in the minimap will target them, and a right click will display a popup menu with options to Invite, Whisper, or Follow.
