How do I show custom content inside the Vanilla template?

iand

I'm attempting to write a plugin that shows custom content into my Vanilla forum when a user browses a particular category. Basically, when the user looks at this category they should be shown the vanilla style but with my content instead of the topic list.

Can anyone point me at some code or ideas that might help me down this path?

Thanks!

you could use this controller function:
public function DiscussionsController_Render_Before($Sender) {
