controller/view/view

[eluser]ZioN[/eluser]
Perhaps I did not explain my question thoroughly.

My setup:
acp/users

acp is the controller and users is the view. The users view is a default page with some general information. On that page I have a little menu with "Add user". I want this to point to acp/users/add_user and I want that page to display my form.

How do I add that last part (add-user)? I tried several options (routes etc.) but I have not found a way to make that work yet.
