About Free Email Blockchain Timestamping for GMail

This extension just tries to add the "timestamp@cert.solidnotary.com" as CC for all emails being composed. You can track the blockchain certifications by logging in into https://www.solidnotary.com using the same email address that was used to send the email. The timestamping takes places every 24h usually but it may take longer for the free service. If you need an immediate proof without sending the document into a Internet server, please visit https://www.solidnotary.com BETA
