I'm sorry that I didn't make it clear: when I said "random contact", I meant a random contact from the user's contact list.

Well, if "All others" is in "Allow list" in "Tools\Options -> Privacy", then, a random contact, such as ok@hotmail.com is OK too. The reason why you need a contact in Allow List is that, only when you are talking to someone on your allow list, the "Enter your message here" textbox is enabled and can accept keyboard input.

P.s. there might be a way to retrieve the actual "Allow List" rather than the user's Contact List, but I don't know how
