Starting OS from scratch: Good idea to set up Admin, test, and user accounts?

[Richie3000]

I once heard that if you're starting from scratch with a new OS, it's a good idea to create three accounts upon startup; an admin acct., a test acount, and your user acct. -- then, you're supposed to operate within your user account for your daily use - leaving admin and test accounts for repair/diagnosis situations...

Any truth to this? Is this a common practice?

Separating your everyday account from the admin account is mostly for those who work from Terminal. It's common practice among my friends with Linux. I don't go changing things often enough to warrant separate user accounts for Admin & Generic Use.

I've never heard of a Test Account before. It doesn't hurt though since you could delete it and re-add it incase something goes wrong while you're testing.
