Registered mail gets you a shiny sticker on the front of the envelope that has a tracking number, and a receipt of what happened. Also requires a signature on delivery, unless you waive that.
It doesn't do thing one to prove the envelope wasn't unandresealed.
You *could* write it up, seal it in an envelope, and deposit said envelope with a lawyer/barrister along with an affadavit stating what is in the envelope dated appropriately. That's gonna cost more than the USPS charges, though. Probably easier just to publish it somewhere and be done.
