Well I can't really explain how it's done but I will do my best.

First this is not in the header otherwise it will go on every page there is.

Second this file need to be added into index.php with a $callname.

Third you need to edit forumhome template and put the $callname in it where you want to locate it.

Or unless you want it in your header you have to do the file stuff in global.php and template header.

I don't really get where you exactly want to put it.
