How do we retrieve the PSP nickname from your program?

Hey guys, I'm coding a lil game right now, and I was wondering how can I go about retrieving my PSP's nickname from my program, so that I can associate it with the player's score.

If you could help me out, it would be much appreciated!

If anyones interested in downloading and checking out my demo, or my source, you can svn it via..

svn co http://jango.sheridanc.on.ca/svn/cst57

username password: cst57 / battlestar

Like X-Flash does

not sure.. never used it.. but I can't seem to get into ps2dev.org for more research, so I was hoping someone here would know. I'm using C btw.. My game is a fan tribute to Battlestar Galactica, and the full source can be checked out at that svn server.
