The Krewe maintains a public transmission list, on which it broadcasts infrequent dispatches when there is news worth dispatching. Subscribing is voluntary; subscribing is also, statistically, the easiest way to stay informed about a parade that does not always remember to publicise itself.
A typical parade cycle produces roughly a dozen transmissions: parade dates, ticket drops, Chewbacchanal lineups, registration windows for the various subkrewe-related undertakings, and the occasional missive from the Overlords concerning matters cosmic and procedural. Filler is not transmitted as a matter of policy.
Unsubscribing is a single click, with no hard feelings on either side of the transaction. The Krewe does not pursue former subscribers across the galaxy.
