It would be very helpful if you could publish the correct website address through which applications should be made prior to the charge coming into effect. I have recently done it and if you Google ESTA you get a raft of sites which look very official but which are not the official U.S. Govt. site. These charge about $45 for making your application and I am not sure whether the application would be valid. In the end I contacted Visit UAS and they gave me the correct address.
