how do i sign up for kms?

Gotta' meet special requirements, not just post count.
Why do you want to come to kMS?
To rape Aran and then run back to gMS and talk about how epic1337 it is?
If you are then don't even bother coming, we will not associate with you.

So unless you have no intention to play the game for fun to mess with content you don't have, you aren't allowed to play it? That defeats the whole purpose.
