I just got my macbook and in my excitement to get going I made a massive typo in my shortname (I didn't think it would be important, just for 'Hi shortname!' type screens, and thus easily changeable) Imagine my surprise when I saw my home directory.
Anyway, I thought as it was a fresh install I could change it using the method describe above and cause very little damage as I had no documents on there.
Is it likely to cause any problems in the future, though? My old home directory is still there, is it safe to delete this? Or should I go through the new user account method to be sure. If I do do this, and delete my old account, will it remove any programs off the hard disk or will they be 'ghost installs' forever?
I'm coming from windows so my mac logic isn't quite what it should be, so please forgive me if these are stupid questions!
