Params: hash

Hi.

I'm really struggling to get a simple contact from to work.

In my controller I have:

def index
    @contact = Contact.new(params[:contact])
    Contact::deliver_signup_thanks(@contact)
  end

I want to pass @contact into 'deliver_signup_thanks' so it can
reference each item via 'contact.name, contact.email' etc

Can anyone tell me how you do this?
