Unbelievable. Awesome hack!!! This is just what I was hoping for especially for a site like mine that hosts forums for so many different subjects :)

I wonder if you could add like X images or something to the forumbit that were links to disable a forum from view.

A very nice usefull hack :)

Thank you.

Great Hack:)

Nice hack

This is fantastic. Thanks for the work!

Now how about adding an option in the ACP forum manager to allow/disallow a forum from being hidden by users? For example, I have a News & Announcements forum that I would not want anyone to be able to hide. If you can add this functionality, it would be perfect. :)

I second this.

Great hack.

Is there any way to alter the code a bit to still display the selected forums when viewing but exclude it from Get New searches?

EDIT:
Maybe if I disable the plugin hooking to cache_ordered_forums but leave the rest enabled?

No. To get what you want, you need to use Andreas's Opt-Out from GetNew/GetDaily, which is essentially what this hack is based on, as said in first post.
