Is it possible to manually call hook_form WITH a valid $form_state from hook_user?
To answer my own question, you can use the hook_form_alter which gives you access to the $form and $form_state.
function jeff_form_alter(&$form, &$form_state, $form_id)
if ($form_id =='user_register')
Cool thing is, in the function that builds your form you can use the ahah helper module (which is why I wanted to do this in the first place) and create some really neat forms.
