Tutorials for creating u32s

Apurva is putting together some tutorials to show us how to build our own u32s in C. I understand Chris Swenson of Dazzletech and MojoMole fame is going to help with this project by adding information for Delphi programmers. Go to Aurva's site and select the U32 tutorials link.
Sorry, due to the format of the site, I have not managed to get a direct link.
