How Do I Get In On The Test Servers?

[Reiterpallasch]

Anyone know how WoW does this? I know they let you duplicate your char to use on the test server but nothing about the sign up process or anything.

I'm pretty sure it's just that: you sign up to play on the test realm, and then you get the choice to either A: duplicate your character, or B: have them give you premade max level character that's already fully geared.
