Changing name of home folder in 10.6

for some reason steve jobs used my email address as the name for my home folder. unfortunately, this is not ideal. i looked it up and there is a way to change it:

http://support.apple.com/kb/ht1428

but it doesn't seem updated for 10.6. Also one of the steps is to just rename your home folder which it will not allow me to do. any advice?

 

why was this made so difficult? it seems like just using a first name instead of email address would have made a lot more sense from the beginning. I can't even follow the simple steps on the page. I'm stuck on renaming my current folder, which is made impossible by apple. there's probably a tricky way to "beat" the computer and trick it into letting me rename it, but it says on the site to rename it "like I would any folder" and clearly this is something that I don't want to mess up, although I have backed up.

 

They should just default name it "home" i've been looking into this online and we're defintiely not the only people frustrated by this
