Whats the code to have a myspace private profile with a visible background?

I think that at the moment, that is pretty much impossible.. unless you're into 1337 h4x0ring script thingerz.

Whats the code to have a myspace private profile with a visible background?

there aren't codes. simply use myspace's profile editor..

whatever colors/background you save on there will be visible on your 'private page' as well.

you can find the link to the myspace editor on your home page under "myspace links" which is above your "my friend space" and the "sponsered links" section. OR click on 'edit profile' and to the right under 'view my profile' and 'account settings' is the link to 'profile editor'.
