BuddyPress.org

when admin create a users he is forced to enter a pseudonym

@victord34 you mean a “username”. That is a WordPress requirement for registration, not BuddyPress. But since BP is a plugin for WP, we use those usernames in different instances.

@victord34 start off with https://wordpress.org/plugins/buddypress-real-names/

@victord34 what do you mean by “change the notif messaging in admin bar. to notif “news” recent pages and articles” ? Notif means what?
