The "free" version has no available settings, other than changing the slug name. But, then if I try to open somewebsite.com/wiki and expect to find a table of contents, all I get is a 404. Nothing ties all the wiki's together, like the way a blog or site map might, so have to make your own TOC. Unable to change the page template; I'm stuck using a template with a sidebar, rather than a full page template, or any other template I desire. I'll figure out a way to use this. Will probably end up paying the $20 premium, as I do find this to be a useful plugin.
