Is it posible?

So... is it posible to make it when it registers when you write random username and password in client?
Just wondering.. and if it is can you please say how? Thanks for your time :busted_co

Well thats a bit vague how about some more specifics ?

Well when you are on WoW login screen, where you type your Username and password, is there any chance when it auto registers there... so you dont need website for registers... ps sorry for my english :busted_co

you would have to modfiy the source code, but it is absolutely possible.
