You guys are really paying 5$ for beta keys? lol.. I picked up 3 when they were giving them away just for signing in with 3 separate emails for friends.
That's all I did, although I just got one for myself as none of my current MMO friends are interested in GW2 currently. I am glad I was able to get one, GW2 looks to have some pretty nice features but I am needing to play it before pulling the trigger.
