multistep form

I have volunteered my time to help with the Notepad-plus-plus documentation project. I am trying to streamline the workflow for approval of translators. I have created a "Translator application" which sends an email with the relevant tokens from the application node. Ideally I would like to just click on a link in the email which takes me to the node where I can approve the translator or deny it. Once it is approved I'd like to have other actions fired.

Hi,

Multistep form is not working in the hook_user case 'register'.
