Ah, I see you're not familiar with it. :)

Well, you add them by direct link manipulation:

The #### is your friend's facebook ID (you can check for it using browser's inspection on a friend's name, will be something like: hovercard.php?id=123456789, for example. So, '123456789' is the ID).

He/she must be a friend of yours, and he/she have his/her CA account (doesn't matter if they don't play it anymore).

You can read more about it here; note that most facebook-related info (such as getting the IDs) are outdated, though.
