Is it only me, or, does it make sense to you, too, to take a convenience (experienced by some subset of PM-receiving users), and swap it for a very probable increase in privacy (experienced by basically every PM-sending user)?
I agree that the email notification is unnecessary, I have to include the full message.
Just indicate the subject and the user who sent it. Or just say that we received a message.
It might not solve the whole privacy problem, but it would at least reduce the number of intermediaries
I'm working on a project that can help make messages more private. It is an external solution, but I believe it can be useful and effective. Soon I will have news.
