Forum:How do you set up a template that will load atuomatically when someone adds a page to a forum?

On this forum when you add a topic you automatically get the 2 templates at the top ^^. The forumheader one and the other which explains that you need to sign your signature at the bottom etc. I want that to happen when someone adds a topic to my forum.

So how do I get them both to come up automatically whne someone adds a topic to my forum? Please help, I am really struggling! (Also please don't suggest the Help:Wiki style forums page as I do not understand step 3 which is what I am asking).
