Funny you mentioned this app. While transferring some data over from XP i happened on it and wondered if there might be a newer version around. I guess no more.
Sarah Dean's personal site is also down. I would say the project is dead. Either she has lost time/interest or something else happened.
I guess download it while you still can. Though it will probably be available on -http://www.oldversion.com/- website.
It "might" not be dead ? But the domain has expired ! Interestingly, it wasn't registered to Sarah Dean ?
