Important: several legacy JINR email subdomains have been decommissioned: nusun.jinr.ru, numail.jinr.ru and nu.jinr.ru.
If your GitLab account uses an email address in any of these domains, you will no longer receive notifications or password reset emails.
What to do (for affected users): Open “Edit profile → Emails”, add your current @jinr.ru address, set it as primary and remove the old address.
Please update your email as soon as possible to avoid communication issues.
If you experience any issues or need assistance, please submit a ticket via https://helpdesk.jinr.ru.
