A program released by Mirablis that allows person to person communications without needing to know exactly when the other will be online. It communicates thru an ICQ Server that allows instant notification of users being online, and storing of messages, files, etc, for later delivery when they are.. Mirablis has been bought by AOL, who most people think will become the demise, as AOL has a competing, but inferior product called Instant Messanger..
