Windows Messenger 5.1 available for download

Windows Messenger 5.1 (English) is now available for download.

I've been running the 5.1 beta for a while now internally at Microsoft. For me, it's great in that I can sign in to both a corporate service and a .NET service at the same time from the Internet without having VPNs and the like set up. I can't confess to being an expert of any sort in Live Communications Server (LCS), but if you run an LCS service in your work environment, this type of connectivity is now a reality.
