-- * Verify I don't yet have a delegation from C
-- * Insert the Grant to my inbox
-- * Record the delegation in the Component record in DB
-- * Forward the Grant to my followers
-- * For each person (non-team) collaborator of mine, prepare and send a
-- Grant, and store it in the Componet record in DB:
-- * Role: The lower among (1) admin (2) the collaborator's role in me
-- * Resource: C
-- * Target: The collaborator
-- * Delegates: The Grant I just got from C
