Leaving an alliance

How in the world of GW do you leave an alliance?

i simply cant figure it out, noone answers in gamechat, and niether wiki has any about it

to leave an alliance if your a member guild click ur guild name on alliance section of guild window scroll down and click leave guild.
if ur lead guild from what i could see u have to just kick the other guilds out of alliance then alliance is over.

aah i see, thank you
