Change: 'In order to use this type as a CCK Sign-up node...'

'In order to use this type as a CCK Sign-up node, there must be a nodereference field from a different type referencing this node type.' text (in function _cck_signup_form_node_type_form_alter(&$form, $form_state) ) comes up in node types.

It says if you want to use this one as a Signup node other node type should reference this one. Which should be the other way.

So my idea is that following text should be there instead:
'In order to use this node type as a CCK Signup it should have a nodereference field to another node type. Example: a nodereference field referencing an event node type. You can set this field using nodereference explorer widget.'

I put an extra example there just to help site builders. First sentence is essential in my opinion.
