Fortunately, with the last update to version 6.6, I discovered that the forum is still very much alive, but under a new address: https://nitisara.ru/forum/.
Perhaps there are other forum members who have not yet discovered the new address. Therefore it might be wise to send all registered members an email with an invitation to the new address. After all, all members have given their e-mail address when registering.
If such an email was sent at the time, then I missed it
and this topic would not have been necessary.
