WSS 3.0 vs MOSS 2007 Comparison Chart
Posted by CJ on September 17, 2008
Just came across this great comparison chart outlining the differences between WSS and MOSS features.
What is amazing is the features you receive for WSS 3.0, which is a free product as long as you have Windows Server 2003 or Windows Server 2008.
