New Hack idea~
anyone know what the coding involved with the mail you send is? if you recall when you are asked to send items in mail it prompts a "how many would you like to send" message...anyway to increase the number without actually having that many?
As far as I know, mails are server side, thus it won't work.
There's probably a server check, because you can actually put any number, it's gonna pop-up saying you don't have enough...
If there's a way, it's not by sending a wrong number, but more by sending a non-existant item. Good luck on that though..
