Adium: Multiple names under 1 alias? (MODS: you can delete)

For some reason I thought I had done this before, but today I was trying to do it with some new contacts and couldn't find out how. Thanks for the help!

EDIT: Arghhhhh! As the page was reloading I remembered that you had to have the window set as a regular window to be able to do that...so disregard my question, I figured it out.
