Can I ask you a question, asides from the fact that it's a shortened form of your thousands of other names, why do you call yourself Blade? Also, why the BZP clarification... on BZP?
Because, well, 'swordman' was already taken at the time. Since it has been shortened, and it's a good short name, I prefer Blade over other things, and it's just stuck. =P
As for the BZP thing, that's just a unviersal tie-in thing.
