I'm not saying this is a bug, anyway, it confused me and I want to report that. On that privacy settings page we have: People Who May...  Start personal discussions with you: And on Contact Details we have: Privacy Settings  Accept personal conversation invitations from...These 2 settings are the same but have different labels. The official term now is "conversation"(?). The internal variable name is allow_send_personal_discussion. Can we have only one term in use, to not confuse people, also for internal variable notations, phrase names and so on?
