+Solanum Implementation
+======================
+
+The ``solanum.chat/oper`` tag is not sent for operators with the ``oper:hidden`` privilege or on servers with the ``general { hide_opers = yes; }`` configuration setting unless the receiving operator has the ``auspex:oper`` privilege.
+
+Operator account names are only shown to other operators. Normal clients will find the tag's value omitted.
