Can you suggest a better URI vs CRUD system for a forum?

[eluser]nullsys[/eluser]
Hi!
Thanks for the tips on route and CRUD.
But I'm still a little confused.
I like the $param system, but I'm still going to have to use the following:

Code:

if ($param1 === "category") {
//Create category
}

Inside each of the create/edit/delete methods right?
otherwise, how else would the controller know which one I want to edit, etc.
