hi! i'm new to this forum and new to the world of mac...hey hey!! 
today i converted from pc to mac and received a new 2 ghz core 2 duo macbook. actually, it isn't new, infact 2 weeks old and this is where i have the problem. the previous owner has obviously gone through the set up wizard and registered an administrator acct. i've been into 'accounts' and edited his details out and put mine in, added my own password but there is no option for me to change the 'short name' to my own, from his, and i'm also seeing his name pop up here and there as i'm navigating about and trying to find my feet. how do i start over and rid this comp of him? so that i am the sole administrator? he installed some software on the comp before selling it and i would like to keep that if possible as i don't have the back up discs.
thanks for any help!
