WordPress Wiki

It is relatively easy to turn a WordPress page into a Wikipedia article. WordPress and Wikipedia both use a similar structure and formatting for their pages. Both platforms use a combination of headings, paragraphs, and lists to organize and present information. This similarity in structure makes it easier to adapt content from a WordPress page to fit the format of a Wikipedia article.

Some WordPress Plugins transform your WordPress website into a fully functioning wiki, or adds wiki pages to your WordPress blog.
