Direct link to subscription page (part two of registration process)

Hello,

I need to find a way to present a link or a form submit button, that will be shown when a user tries to log in to an inactive account. The link will take the user to the second part of the registration process, ie. the subscription choice page.

I’ve tried manipulating the action variable, but it either took me to an empty template page, or to part one of the registration page.

Thanks,

Owen
