name change?

ok..i have no freaking clue what im doing here! very basic knowledge of ALL this computer stuff! my question is, is it possible to change the name of my imac? i guess when i got it up and going, somehow it got named after me! so im assuming the would be my network name when i go wireless? which would end up being my whole name! it says, "computers on your local network can access your computer at: john-a-doe-imac.local" (my name instead of john doe). thanks for any help!

How about selecting the Edit button.

geez.... thanks there bobby!...was wondering if it would change any registry info by changing the name also.....

This is not Windows - there is no registry.

thanks....
