Messenger Plus Live is an add-on for the Windows Live Messenger which adds a multitude of new features to the main program. Messenger Plus Live works with Windows Live Messenger 8 and 8.5 and can be used on Windows XP and Windows Vista.
The new Messenger 8.5 for instance is missing several features that the previous versions had included and Messenger Plus! Live adds them again to the software. Besides offering the build in functionality it also supports user created scripts and offers hundreds of them on the official website.
The main features of Messenger Plus Live are Tabbed Chats, Quick Text, Custom Sounds, Colors and Formatting options, Messenger Lock, Contacts on Desktop, HTML Chat Logging and Personalized Status. Several of them are pretty useful already but the real beauty are the scripts that can be installed as well.
It would be probably a good idea to start with the coolpicks category in the scripts directory which contains more than 20 preselected scripts chosen by the developers of Messenger Plus Live.
This is a great tool for anyone who is using Windows Live Messenger 8 or 8.5.
