GAME about a new account.

So guys @Frankengoof did this game earlier, but I'm gonna do it now! 

In this game, I've made a new account. The first one to sends a message to this member wins! 

Every day you will recieve 1 hint, to better know who it is! Good luck! 

Hint 1: The flag of this member is the flag of a country where a magic school is in in the harry potter books (it could be hogwarts, but also one of the two other schools who compete in the tournament in the goblet of fire)!
