Ability to edit private content verification email
Currently users are able to edit the registration invitation email, password confirmation email, and password reset email within Settings > Website > Private Content as seen in the Knowledge Base.
There is one more email however under the use case of a visitor registering themselves after clicking 'Log in' on a website that supports private content which is not editable nor customisable yet. This would be the verification email that gets sent out upon a new user registering.
Ideally users who have set up Private Content should be able to customise this verification email as well, down to the email address it sends out from (ie. something other than firstname.lastname@example.org)
