Contacting the owner of a forgotten page

Hello I’m trying to put together a website on remarquable french band Tiemko (if you hate them this message is a waste of time LOL), so my first move was to create an account named Tiemko.

But the name is taken ( tiemko (tiemoko) · GitHub does exist indeed), so I was about to forget it and move on… Except that nothing has ever been uploaded on it since 2013 ! Alas I cannot reach the owner with the address tiemko@github.com. If anyone can ask him if the address can be recuperated it’ll mean a lot for sure !

Thanks for reading,

Jean-Marie Tschanz
