According to the Windows Live team blog @ Inside Windows Live The Windows Live Essentials Wave 4 software suite will go public tomorrow! Live Essentials is several free cloud oriented programs offered by Microsoft. These include:MessengerLive Photo GalleryLive Movie MakerLive MailLive SyncLive SkyDrive - a central location for uploading anything from any of the live services, or directly from your computer. Just like your inbox, it has "ever expanding" storage.Office Online (Microsoft Office for free in your browser!)And more! I've personally been waiting for this for months now, and I had a sneak peak at messenger via a leaked build several weeks ago, however the build was deactivated a short while ago and back to 2009 it was for me. **EDIT** The download went live at approximately 4:40 PM AST yesterday. There is major revisions since M2 (v 15.2), most for the better. I'd post screenshots, but I would have to edit too many of my friends posts etc out.
