[xwiki-devs] Wysiwyg editor questions

Hello, I am dealing with the following issues... 1. The default properties available to add to a class is a limited list. Is it possible to extend that list? Is it possible to provide a Wysiwyg editor embedded in a class, without giving users 'edit' rights to the wiki-page? I am just looking for a user-friendly text-area where users can add descriptions that can be stored and retrieved as objects. 2. How to store the contents of wysiwyg editor to a file? 3. Is it possible to launch Microsoft Documents, text files and HTML files stored on a server or the local file-system in wysiwyg with URL path as the input? If no, can you please suggest any alternative solutions? I'd appreciate your help. Regards, Archana Mettu.
