The cutting-edge XenSource website reduces maintenance costs and saves time by enabling content to be updated, edited and approved quickly with centralized collaboration and workflows for its distributed teams. Running on the Microsoft Office SharePoint Server 2007 platform provides the added advantage of feature-rich functionality so that blogs, wikis and other functions can be used immediately or turned on when needed.
XenSource selected Resolute because of their technical depth and agility. Roger Klorese, XenSource senior director of product and solutions marketing explained, “The entire team at Resolute were responsive, flexible and delivered a world-class site quickly and on budget, and helped us to leverage our investments in Microsoft and SharePoint.”
Why did they choose SharePoint, aren't there enough of those CMS solutions like Joomla etc? Just wondering... Here's the link.
