how can i add a menu link that goes to an external page

i started a new blog and i see that there are two pages it starts out with:

1. Home
2. About

i want to add a third one but instead of having it load up an internal page, i want to have this go to an external link. is this possible ?

Admin Dashboard -> Appearance -> Menus

If the theme is WP 3.0 ready, you will have an option to add a custom link (ie external link) on the left side, and you can drag and drop it into the order you want.

Justin Tadlock wrote an awesome post about 3.0 menus – http://justintadlock.com/archives/2010/06/01/goodbye-headaches-hello-menus

If your theme isn’t 3.0 ready, I believe you can still use the custom menu widget.
