Hide Hack?

[x-Treme]

The hide hack that is included with xthreads that hides a forum or category from the index...is it available as a separate plugin? I need to hide a certain category from appearing on the index, but I don't need all the other features of xthreads.

Any possible help with this? Anyway to use templates and conditionals maybe?
I've tried everything I know of trying to accomplish this, but no luck so far.
