Ha, I think you have to click on "Save" or something - it didn't go through yet -- I had that happen to me in the beginning. You check the person's name (it says "check all" i think, even if it is only 1 person) and then you click save----it's not you, it is confusing and glitchy. Keep trying,
sorry a bit buggy and not clear --- If worse comes to worse, you could try friending me (on your USER CP , the control panel, click on "Contacts and Friends" and you should be able to type my name in and click on "Add" or something
