Issue with the devise

I am using Devise and want to override a method from a controller also
is a different way for signup.
I am using RAILS = 2.3.5 and DEVISE= 1.0.8
I tried using

class Mycontroller < Devise::RegistrationsController


and also
devise_for :users, :controllers => { :registrations =>
“some_diff_controller” }

But still I am finding that the method is NOT getting overridden.
Could you please suggest anything over here

Thanks in advance

Thanks and Regards
