Return of Reckoning

hello all,

been trying to get an add-on or (something) so we can connect guilds together and have more coordination and more fun.
now ive noticed all of sudden this thingy https://discordapp.com/ and its free its not in game sync yet but it will be bit later on it seems since they say coming soon... wot do u guys think ...>??? and or does anyone maybe knows an add-on to for example get ur allaince closer together..

regards a fellow player

We are using Discord within our guilds. Works fine and it is clean. Doesnt demand as much resources as Skype and TS
