Microsoft Live Messenger 8.2 will support multi-user login

The Messenger development team is busy preparing the next 8.1 Beta version, but the development plan for 8.2 has already been clarified. What does the word Polygamy mean?

I guess you've figured it out. It’s a third-party patch that allows multiple WLM exe files to run and log in to multiple accounts. Windows Live Messenger 8.2 integrates this function, so this plugin is no longer needed.
