System.user and generalizing/specialization

Hi all, this is probably a laughably simple question, but I'll ask it anyway. 

I have a single object, employees, which is generalized o/from system.user.  the employees object has FirstName and LastName attributes. I've created a NewEdit form with the 2 bl name fields as week as the password, name and other fields from the system.user object. When I run the app locally, I'm able to create employee records, but don't see them in the accounts pages. 

What am I missing?

Thanks for not laughing too hard at this newbie.
