that would be good but i dont think that a lot of community's members play GW (maybe i'm wrong).
And since that the launch date of Guild Wars 2 has been set to the 8-28-12, I suppose that a part of them will play to it.
it's possible that after 1 Month members of the guild will be inactive or leave the guild to play to gw2 and i dont think that is what you want.
