My HD recently crashed, took it to apple for my replacement, and the Customer service was great.

Only problem ive had is that the tech people reboot my comp with 10.5 and created my admin name. I have gone into preferences to change the admin name, but the changes i make are not shown when i i open finder or when i am asked to give authentication for certain installations.

I just want to change the name, and have it shown in finder screen
