Well, as it currently stands, only you would see any "status" change reflected in your account, and that'd be on your "My Account" screen. That is currently the only distinction between Subscriber and Grandfathered on the site. If any further distinctions are implemented (features that're extra-cost, for example) we'd offer a steeply discounted "upgrade" path.
But all functions that check membership level currently act differently only if someone has joined since 9/4/2001 and isn't a subscriber.
