chapo.chat doesn't allow to sign up, for how long is it going to stay closed?

Today i found out https://chapo.chat is finally a thing, but as far as I can see, they don't allow anyone to register anymore. I tried to look in /c/main, but i don't see any post about closing the subscriptions. Does anyone know why it's closed, and for how long the lock will last? Maybe they announced something in their discord?
