Guild Wars 2

I saw the press release saying that we’re getting a double experience weekend. That left me with a few questions:

1. When does it start? and …
2. Does that include crafting XP? WvW XP?
3. Does 2XP stack with experience boosters, like the birthday booster?

To my knowledge something like this has never been done before, and I seen no details ye.t So unless someone knows something more you’ll have to wait.
