ability to add a guild to the list, and warns you when u are in raid/group with someone from that guild.

Please provide any additional information below.

in the pug arena atm alot of unknown guilds are popping up making pugs and then ninjaing everything, or simmular events.
i try to play by the rule that i wont "blacklist" a guild before they accually do something like this in a raid that im in or one of my irl mates
was in raid with them. having this feature would alllow me to quickly know if i should leave my VoA25/10 pug and or discuss the incident with
that player from that guild or such.

bottom line, need this badly for pugging, and not grouping with guild/ppl that are known ninjas. hope you will consider this :)
