I set the hook location to forumhome_start and the plugin is active but nothing happens when I try to use it.

the same happens to me !
until I realize that if you want to use this plug-in
you must go to AdminCP > and create a new template

and name it ( page_whateverYouLike )
and then put into the body of the template the html code for your page !

final step is to call your page from the browser :

http://www.yourforum.com/index.php?page=whateverYouLike

and that's all
