Oddmuse is a Wiki engine, a CGI script that creates an entire Website with editable pages. By default, anybody can edit the pages. The entire site can be made read-only, and single pages can also be made read-only. In that case, only people having the admin or the editor password can edit pages. This way, the Wiki can be used as a cheap, simple, and easy-to-understand content management system (CMS). The site can also be switched to Weblog style, such that anybody can post comments, but only the editor can add new pages.
