Messenger Plus! Live is an add-on for Windows Live Messenger which adds lots of features and extras that make your instant messenger easier, more useful or just tons more entertaining. Remember that Messenger Plus! is not a chat program, it only adds functionalities to Messenger, it can't be used as a standalone application. Messenger Plus! is not an official add-on from Microsoft. Microsoft is aware of its existence, it tolerates it, but you can't contact the Messenger support team to get help on a Messenger Plus! feature. Also, Messenger Plus! has nothing to do with Windows Plus! or MSN Plus!, both products from Microsoft. That being said, Messenger Plus! is still, by far, the most popular and respected add-on for Messenger and thus, since the year 2001.
