Using a piece of paper is the best way to inform a jw, for many reasons.
As i said:
"Start a 'chain' letter USPS and email. Brief to the point. If you want to help someone specific but afraid of USPS stamp showing your city, ask someone else to send it from another state. It could be the UN issue or any other... Most people read letters, even if the burn it later. Other wise how will they ever know?"
