How best to create a new primary user account?

[Kraniac]

After reading the Mac docs, i was preparing to DUCK. Actually, I was preparing a raid on my kids stash of everclear and gatorade. Luckily and thankfully, you included a link to changeshortname. I hate gatorade. And, you held off on the fois gras crap...dont get me started on banning trans fats. My partially hydrogenated frosted flake oil is close to my heart's walls. Thanks for that and ill decide whether i should just do this crap all over (clean install) or try to just change the friggin names.

Now, i wish someone could help me with the topic i made directly below this one regarding identifying matched pairs of RAM.
