Is there a way to block fora?

Is there any function in the board to block entire fora?
i.e. if I don't want to see a play-by-forum thread or someone's personal campaign discourse?

AFAIK there is no way to block bits from appearing if you look at new or latest posts.

You can exert some control over email notifications via (your name at the top) > Preferences, but I don't think that was the question.
