Is it possible to have a forum (not a category) hidden from the installation index, while still allowing all user groups to view it? I'd like to use this hidden forum as a blog; having all posts within it be displayed on an external page (i.e. the blog), and allowing all user groups to view these posts on the external page. If the forum was open to view regularly, then it would pretty much defeat the purpose of having the external blog page, when they could just go to the forum; but I'd like to have a more integrated approach.
I was thinking to completely structure the index.php to have be static in regards to the forums displayed, just to hide this one single forum, but that is obviously not very efficient. Is there a way to exclude an ID being displayed in index.php? Or any other work-around will do.
