掲示板 Forums - Unlinking my deleted discord account from renshuu

I deleted my discord account to start anew with only the servers that matters for me now (for personal reasons I pressed the delete account myself). But now I realize I can't just unlink from renshuu.org, but only from the now nonexistent discord account.

What should I do? It's not a big deal in the end if this doesn't work, but I'd be nice to have a way to fix it.
