ArcadiaLogos is an addon to rapidly spot your closest allies and your sworn enemies, when used in conjunction with player-created logo packs, it identifies friends and enemies when you mouse over them (or optionally target them), by showing a logo based on their guild.

Initially developed for the webcomic conflicts on Dark Iron, the addon is now extensible to any guild or groups of guilds who create a logo pack (Instructions on creating such logo packs are included in the logopacks.txt readme file).
