Sounds impressive! I'll try to get it when I get back to my residence on Tuesday (I stupidly left my code there -_-).
And I'd assume that the 'talking to people who aren't your friends' works something like this:
You (person A) are chatting with your friend (person B). Person B invites a non-mutual friend (person C), and you guys can all talk together. Using the quick-access friend code/list, you can easily add this person so you can talk with them independently.
And I thought there was going to be a limit of four??
