@inherits LocalizableComponentBase

@* The root's personas (/clientapi/avatar/private): each one used in turn, a new one made, and one deleted with the
   login's password, asked first (everything public it had goes, with the groups it owns). One the server's staff
   suspended or silenced says so; a suspended one can't be used until the suspension is lifted, but may be deleted.
   Personas are never linked to one another: no server, PrivaPub's included, shows that they share a root. *@
