I have a different user for each of my own work areas on my system. This is to keep bookmarks, files and other defaults separate.

Several "users" are generally logged in at once and I just switch between them when I change which project I'm working on in that moment.

I'd like to keep track of when I've been working on different projects and I figured tracking these sessions would be an easy way to do this, however I don't know if there is a log available that knows which user is active at any one time, or how to create such a tracker.

Thanks! Woody
