Evoq was previously known as DotNetNuke (DNN), and has recently been changed through its own rebranding effort, much like the way OpenERP became Odoo. So, according to their own news release, DotNetNuke is no more and is now to be known as Evoq. While not nearly as popular as the other three listed, Evoq has the distinction of being a Windows Server-based solution that uses Microsoft's .NET platform. Some big names using Evoq for their CMS include Hilton and Samsung.
