Creating and managing accounts in GNOME

[Alex]

Hi,

I'm an old-school Linux user who's always done things from the command
line. I have a fedora29 desktop with GNOME and need to change the
default login user. Where are the GNOME user management tools to do
this? Certainly nothing in Applications except "Settings" which
apparently isn't for managing users.

All the documentation I have found on this no longer seems applicable.

Is fedora29 now using wayland?

Thanks,
Alex
