Can you put 2 email addresses to the same user?
I don't think so.
I tried today, with a "," between two e-mail addresses, to see if it would work, and only the first one got the e-mail.
That's a good suggestion for bOS team, to enable multiple e-mail recipientes, separated by "," for example. I don't think it's too hard to implement.
