Take C1 CMS for a spin!
»We have been following Orckestra closely for some years now, and have used C1 CMS for a number of our major clients. It has a wide range of ready-to-use modules, both free and paid. It‘s very easy to set up a new website and C1 CMS makes it easy for customers to access content through the administration interface while we, in parallel, continue to develop the website. We are also pleased with the excellent scaling options C1 CMS offers. The built-in migration tools allow you to start with data in XML files for very small sites, and easily upgrade at a later date to SQL Server or move to cloud hosting based on Windows Azure hosting centers around the world«.
