Indeed I do, the handle I am using is the one I was assigned on the systems of the University of Oslo and I even link to my personal page there from my profile here - and link back to my profile here from there, thereby proving that I am who I say I am. My reason for doing so, is that I have no reason not to it. Furthermore, I tend to take people a bit more seriously when the info they have provided about themselves can be verified (although thats not to say that I despite anonymous users in any way - they have their reasons).
