Could you give a bit more details about that please?
If you want to add a user, open up the Mandrake Control Center (MCC) and clic 'System' and 'User' and clic 'Add a new user' (This is like that on MDK 9.0 at least .. shouldn't be different with MDK 9.1). Then follow the wizard to add a user.
You can also open a consol, login as root (su + enter your password) and type 'userdrake'. Then just answer the questions..

No what I want to do is read on sudo and then add a exitsing user to the sudo file, so that the user may sudo apps and stuff.
