Private correspondence should always remain private and should not be published publicly.I hope you agree that publishing my personal message here is a mistake.
I assume you've sent the same message to many users, and if they choose to answer your questions, they'll also quote the questions from your PM and post them here. In this case, I don't think this requires confidentiality.
You are right as always.
Just to name my project as "ragbag" it is not necessary to quote a personal message.
