Ubuntu User Days is a very informative one day session geared towards beginner and intermediate Ubuntu users, as well as people who are interested in using Ubuntu.

We have 14 classes covering topics ranging from installing Ubuntu, finding help, equivalent programs, using IRC, getting involved in the Ubuntu Community and more. We have enlisted the help of many talented people to lead these classes throughout the day.

I’ve watched several of the sessions and picked up a few tips on different things despite being a fairly seasoned linux user, well done to the team behind it :)
