[X4U] Get rid of login window

[Paul Moortgat]

A sister in-law got a Macbook G4 (10.4) from a daughter who bought a  
new Mac herself.  This G4 has a login window which my sister in-law  
doesn't like.  She want's to get rid of.
How can I do this?  I try to avoid to start from zero.  Her daughter  
imported all her soft from a G3 she also has and will now move to a  
store room.
Long ago I advised them to buy a Mac if they want an easy computer  
life.  They did and they're happy with.
