Get an accounts last name!

Last Name!
Probably the easiest step of all. Once you have the username and password this can easily be obtained thanks to Nexon's lack of notice.
Log onto the account at Nexon.net and select maplestory. When you get there select support, and under it E-Mail of inquiry. Then select the "Log a Ticket" tab. The Person's FIRST AND LAST NAME IS RIGHT THERE! It will say "Contact's name" then there name.
