This was the first time that I got a full impression about what can be done with MCMS.Rapid.
Actually this is really a great product filling many of the feature gaps MCMS has out of the box. The most interesting thing I saw was the SharePoint Webpart like modeling of templates. No VS.NET and no programming skills are required for template development! Everything is done with XML files and even those don't have to be edited manually but with a nice GUI.
Really great stuff!
