What I need to do is change my account short name and home directory name. What is the best way of doing this? Also will i have to set everything back up after doing so? For example, my itunes library is in the directory /users/NameExample1/Music/iTunes. When I change my user name am I gonna have to go into all my programs and update the settings to /users/NewName1/Music/iTunes or will it automatically update to this? Are there any problems that could be caused by me changing my account user name?
