"A fantastic app/CMS. It has great layering so you don't need to be an expert to start... and then as you build your knowledge can switch to more complex developer's languages like C#. Combine this with MVC, Razor and you have a cutting-edge ready to use platform that is simply a joy to work with." bluemeansgo
