Posting threads in Categories.

Hi there!

I am unsure whether this has been suggested before, since this could be named so many things and so many suggestions to look through, so I apologise in advance.

I believe my self to be relatively skilled with Xf, however I seem to be missing a feature I desperately need/want in my forums;

I want to be able to display a thread inside a category. Such as rules for the category, yet I can only place threads inside a forum, inside a category.

Is there an easy tweak or mod available? I've looked through every single page on the plugins/mods for something for this, got no where.

Thanks in advance ^.^
