Do you mean boards for threads like this one? You cannot create them because the feature (called Forum) is not available to wikis created after November 2016. Your wiki has Discussions. Discussions allows wikis to create custom categories; supposedly serving the same purpose as Forum boards. If you are talking about wiki-style forums (a.k.a. DPLforum), then you need to create the board page. You can find instructions for that here.
