I would like to start a Wiki, but my audience is not the type to learn to 'program' in Wiki markup language. Is there a good theme/plugin or even a non-Wordpress Wiki that is easy for visitors to update themselves? It would be great for users to edit articles as easy as creating a post in Wordpress. I fell if the Wiki is to hard to write articles with my not-so-smart audience won't be able to create content themselves and it will be just me doing it all the time. Ideas?
