Board Thread:Support Requests - Getting Technical/@comment-30802928-20161220183000

I know that Wikia are changing all the new Wiki's to 'Discussions' instead of 'Forums' and all that business. What I don't understand is: I can't create board on my 'Discussions' I can only post threads that people reply to. Does anybody here know how to make a board, instead of a thread (on the updated version)
