How to remove user name from MeMenu in Unity (Ubuntu Natty)

The newly released Ubuntu 11.04 (Natty Narwhal) features Unity shell interface which displays the current user name the top right of the panel (MeMenu) that adds a personalized feeling to desktop users.

However some users might not be comfortable to have their username appears on the computer screen, especially when they are working on a publicly accessible computer or when they do not want their username to appear on screenshots or screen-casts of their desktop.

So to remove the username, one only need to open a console, and run the following command:
gconftool -s /system/indicator/me/display –type int 0

Alternatively, you can also choose to display your own fullname on MeMenu. You can do that by running the following command:
gconftool -s /system/indicator/me/display –type int 2

You return to the default setting of displaying your current username, by running:
gconftool -s /system/indicator/me/display –type int 1
