"In this article, I am going to introduce you to an outstanding graphical tool, found in the GNOME desktop of Ubuntu 9.10, that allows you to manage both users and groups. Because this tool is a part of the GNOME desktop, there will be no need for any installation (that is, if you already have GNOME installed). So getting up to speed is just a matter of firing up the tool and understanding how it works.
"The user and group management tool can be found in the Administration sub-menu of the System menu. The entry is this menu will be labeled “Users and Groups”. When you first fire this tool (see Figure 1) up you will notice you can’t really do anything. Before you actually use this tool you have to unlock it by authenticating with your users’ sudo password. To unlock this window click the small “key” button (in between the Help and Close buttons) and then enter your sudo password. When you do this the rest of the buttons will become available. Now you can click on a user and modify that users’ properties."
