BuddyPress.org

I’m working on a solution for this as well, and I made it very easy for myself, I made a category called wiki and made my subcategories for the wiki in there. Than I placed the wiki pages in that category and made sure that everything in there isn’t able to show up in any listing.

It’s a very easy solution, and you can even make a different layout for the posts in the wiki category.

Though, I am still looking for a way for users to make posts and/or edit posts in these categories and how I can moderate those posts easily.
