I just got my final paperwork from Tesla and read the details of DocuSign. It says that if you agree, Tesla will send all future documents through DocuSign to your e-mail address. It says you can change your e-mail address at any time, which is good. But then it says that all you need to do to change it is send them an e-mail with your old address and new address, nothing else. That sounds like someone could hack into my e-mail, ask them to change e-mail address and I'd miss future notifications, and not be aware of anything. I know Tesla reads this forum, so I'd like to suggest they add a security step before changing someone's e-mail address.
