There are two types of "forums". The oldest is the wiki-style forum. This is the one you linked to in your example and it is still available to all (well, almost all) wikis. All you have to do is for the feature to be enabled/re-enabled for the wiki. Essentially, it works just like talk pages but has a few special pages (like Forum:Index) and other features to help organize the conversations.

The second and newer "forum" is the feature called Forum. This is no longer enabled/re-enabled on wikis so the only wikis that have it are ones that have yet to deactivate it. Forum is being replaced with Discussions/Community Feed; what your wiki already has. Forum stores each comment as a separate page and then provides special thread pages for viewing the conversations. This is what Community Central currently uses. It is essentially the same as message walls and comments.
