Guild Greet is an Addon that Greets your Guildies when certain Actions take place. These Actions are Login & Relogging. It also Congradualates them on Level Ups and Guild Promotions.
You may also set Alias's for your guildies, along with putting their ALT/Toon with their Main Character.
Some people may find this Addon Annoying and it may seem Spammy for larger Guilds!
