Did Nexon give an extra character slot for the new characters?

Don't we have 6 slots per world already? Do you all seriously have 6 characters on one world that you can't delete?

7 on older accounts.
I don't really want to delete any of the characters... plus I'd have to get a second computer running as storage mule because my main account is packed densely.

Anyway, there's also the mechanic coming.
