Administrative functions like are hands-on in this release of WikiWriter, but will be built-in for later releases.
A backup of each page is saved to that page's ".bak" file when you edit and save a page. To use a page's ".bak" file for recovering the previous version, open the file in a text editor, copy the relevant section, and paste it into the current page (in the WikiWriter edit box or in your text editor). It's good practice to use Preview while editing to check on formatting and changes, and use Save only when you're satisfied with the editing session. Otherwise, using Save repeatedly during the editing session on a page will give you only a small-step, last-change backup as a safety net.
You have to know CSS in order to tinker with the display format innards. See the references at [AllMyFaqs CSS] for CSS information. Dave Raggett's CSS introduction at [http://www.w3.org/MarkUp/Guide/Style] is a good start for CSS beginners.
Distribute WikiWriter sites by compiling the WikiWriter site into a single file with an .mht extension, or by webifying the project into HTML pages then compiling them into an HTML Help *.chm file with an external compiler. If your site uses graphics they will be included in the compiled file. The compiled file can be Zipped to achieve up to 75% compression.
