I make a couple of different users just for myself. I like to play around in the computer, so when I do mess it up real good, delete one and copy the profile etc., from the clone to make another. Reminds me of the SuSE 7.3, when you logged in as root, the default background was a bunch of exploding bombs on a red backdrop. Kinda a reminder of where you were. Well one day I changed it because I was a little thick in the cranal cavity I guess, and thought I'd never mess it up. Some things are unrecoverable......lol Had to reinstall the whole os.
