@jaredvd – When i attempted to create a wiki awhile ago using a modified version of wiki lite I used the voodoopress guide (http://voodoopress.com/how-to-post-from-your-front-end-with-no-plugin/) and then changed the description textarea to use the wp_editor (https://codex.wordpress.org/Function_Reference/wp_editor to get a front-end ‘create article’ page.
Just make sure you change the ‘post_type’ to incsub_wiki to turn the articles into wikis.
You will also probably want to wrap the form with a is_loggedin conditional.
