Affordance for manual "use" records

[stuartpb]

Say that I create an account on disneyworld.disney.go.com and, at some point in the future, Disney gets their act together and makes a good account management system at Disney.com.

The right thing to do here would be to change the password for a hint related to disney.com, but in the interim, my account is going to be using the hint for disneyworld.disney.go.com. I need a way of manually saying "use the hint and everything that I have set up for disneyworld.disney.go.com when I'm at disney.com".
