...that allows you to scan for un-guilded people and whisper them?
At least 5 or 6 times a day, I get whispers from people asking me to join their guild, usually in the form of 5-6 sentence spam macros. It's really fucking obnoxious.
"lol just join a guild, problem solved"
I don't feel like joining a guild. I'm a casual player who uses Group Finder for raids and doesn't do mythic; I have no use for a guild.
