CB Paid Subscriptions

When attempting to accept a shared subscription, but not logged in you are asked to login or register. Upon login it should automatically accept the shared subscription instead of requiring them to click a link they already clicked. This should be doable by simple adding the accept link as the &return for the redirect.
