Fortnite tournament website etc?

Moinsen sorry does anyone know a website etc where you can register yourself and your clan for a fortnite game?

There's no official website for it.

Clans do not need to be registered, you can just found them and implement them in your name.

I know I said but if there's a page like Fifa esports where you or your clan applications can to play against others

Oh ok.

I searched for it and found it here: https://gamertransfer.com/Turnier-4-_fortnite-team-on-all.html
