XF 1.2 Add custom sidebar to Forums page?

Okay, so I have an edited version of my Users Online sidebar, that integrates the Staff Online and Members Online like this.. http://i.imgur.com/kek9lpF.png

That shows up on all of my pages I want, except my Forums page. Why is that? On my forums page, it has the old/default Users Online sidebar still. How can I add this edited version of the sidebar to my forums page as well?
