Name change question

Talking about IGN changes, how does that CS Name Change item work?

When you buy it and type in a name you want, does it check immediatly if the name is available (And when it's not, it's rejected)? Or can you enter a name and the name change is checked when a Nexon employee changes it during the next SC? Does anyone know how this works?

I've name changed 3 times. After you click "buy" you'll be prompted to select a new name. If it's not available or can't be used for some other reason, a message will tell you so. It's only after you've selected a name, verified it, and pressed "Yes" a billion times (I think it asks two or three times "Are you sure?") before the NX is charged. Then your name gets changed during the next Server Check.
