As you probalby know, all User types are derived from the base object called "Object". (Talk about nameing policy)
When you make a list it doesnt matter what you said you are storing in it. You are storing the "object".
So when it comes to access the objects fileds and stuff, you need to "cast" the object back to what it originaly was.
