Does anybody know why Lang-8 stopped accepting new membership?

I’ve heard a lot of good things about this language exchange site called Lang-8. I was going to check it out for myself, but was rerouted to this thing called HiNative. Later, I learned that Lang-8 stopped accepting new enrollment/subscriptions in March of this year. Supposedly, enrollment has begun again, but it appears that new subscribers are still routed to HiNative.

Does anyone know why Lang-8 stopped accepting new membership and whether or not they plan to accept new members in the future? Any information you can provide on this language exchange program, especially with regard to its status — past, present, and future — is appreciated, even if what you have is speculative.

Thanks in advance.
