Earlier this year, GitHub changed their API to make it so we could repeatedly send invitations to people, spamming them. Invitations were stopped because of this. @andresilva sent a PR fixing this issue, so we can send them again. Each person who is a maintainer will receive one more invitation, and then they won't receive any more. PR: NixOS/rfc39#6 Thank you, @andresilva! My apologies to those who will see this last invitation as more spam.
