There isn't any message board built in, per se, but there are ways to ask questions. If you want to ask a question or discuss something about a certain page, you can use the discussion tab at the top of the page. It brings you to a second wiki page that you can edit with your question. Just make sure to sign your contribution to the "talk" page. You can do that by adding --~~~~ at the end. If you have other questions, see if you can find a page close to that topic and use the talk page for that. Otherwise use the Village Pump:

If you just want to test things out, you can try the sandbox:

And of course, you can always ask here if you have more questions.
