Messenger Plus! is an add-on for Windows Live Messenger (WLM) that adds all kinds of features and extras. There are millions of people who use WLM yet don't know that Messenger Plus exists, so we thought we'd take some time today to explain the benefits of the add-on and all that it offers.
Before we dive-in, we wanted to point out that Messenger Plus! is considered Adware and that's because when you are installing the application, it will ask you if you would like to become a part of their "Sponsor" program. By default it is NOT checked. They explain that their sponsor program is adware that helps keep Messenger Plus running. I don't know many people who enjoy adware on their computers, so be sure you pay attention. If you do, you will have no issues.

In the past, people have asked if there are any spyware concerns with the program and there aren't. Messenger Plus is a reputable application that has been around for a long time so there's really nothing to worry about, other than paying attention during installation. But that's something you should always do.
Background info:
For 7 years now, Messenger Plus has been available to Windows Live Messenger users. As of mid-July, 50 million people use the add-on on a daily basis. The current version is 4.6, and it's a free download that you can find here. Installation is quick and painless, but again, make sure you pay attention while doing it. When you launch Windows Messenger for the first time after installing Messenger Plus, you'll be taken through the configuration process
