Separate iTunes libraries for multiple users

There was a post a while back about managing multiple users and one itunes account. I was not able to find it in the search, hence am starting a new thread with the info I found. You CAN create multiple libraries on one computer using one iTunes account instead of managing your music through the use of playlists for each user as the last thread suggested. Look at method 3 on this page http://support.apple.com/kb/HT1495 . Thought it might be helpful to those in similar situations as mine, two teen girls and my taste in music rarely crossing paths!
