Allow me to add to what I wrote prior.
This part of the forum, "Wiki Discussions" is used as such.
Pages in the wiki will each have a tab at the top for "discussion" that will lead folks to here, the forum. This gives each page in the wiki a place to talk about what's presented on the page. This includes pages that describe how to use the wiki - almost all the pages in the wiki system allow for discussion. When someone clicks this "discussion" tab, if there is no existing discussion, the system automatically creates a thread. If there is already a discussion (the thread was already created), the person will be taken to that thread.
Hope this clears it up a little better and gives you more of an understanding. And of course, it'll all make more sense when you start digging into the wiki.
It's coming along very nicely, too
