Private notes for initiatives

Initiatives are moderated a priori by the admins. As an admin I might want to contact the author(s) to ask for more info before publishing or when setting the date collection period. As of today I can go to the user profile and start a conversation but I might be lacking the context of the petition to have an efficient conversation + if there are several authors (promotion committee) I cannot start a group conversation so I have to contact them all separately. The proposal here is to mimick the proposal "private note feature" to allow for these conversations to happen. Checkout mockup in joint image. Belgium Federal State would fund this.
