Sigh. Gmail at it again. Cannot send the CCC invite link. Docs and invite are in the discord announcements. If you're interested and not on the discord, send me either an email or a PM here.

Sorted out the gmail thing: I delete messages in my IMAP email client. Google removes all labels from such messages but *does not delete* them. For years. A normal filtering search for e.g. "Trash:" finds nothing. A magic keyword search finds 175,000 from over a decade.
