The Telerik r.a.d.editor is a high-end WYSIWYG content editor that enables non-technical users of Microsoft Content Management Server (MCMS) to create and manage rich HTML content as easily as writing a document. Featuring a familiar Word-like interface and a set of intuitive tools, r.a.d.editor can quickly replace the default HTML Placeholder in MCMS-based applications.
r.a.d.editor MCMS edition is available at no cost to all customers of Microsoft Content Management Server. However, this is not a freeware, but rather a commercial product that is sponsored by Microsoft.
