Adobe offers an FTP-capable client-side program called Contribute that can be used to edit an already-built site in a WYSIWYG fashion. Today, an Adobe representative has stated that Adobe DreamWeaver is not needed for the insertion of Adobe-specific mark-up tags that prevent a non-technical site manager from editing predefined areas of the site. Thus; according to Adobe, Contribute is a viable CMS solution even when the site developer uses any common editor - even NotePad - rather than DreamWeaver for the insertion of the "Not Editable Here" type of Adobe-specific mark-up tags.
However; for a variety of non-technical reasons, Adobe products are often not a desirable solution for the aforementioned scenario. This posts asks; is there an off-the-shelf program like Adobe Contribute (as described above)?
This post is not seeking server-side options like; for example, Joomla and WordPress. Your helpful references will be greatly appreciated.
