Send instanced pings and give useful error messages Based on discussion on -c barnowl, switches zwrite adehnert => ping zwrite adehnert -i test => no ping zwrite adehnert -c test => no ping to zwrite adehnert => ping zwrite adehnert -i test => ping zwrite adehnert -c test => no ping Pings match the class & instance of the message they are associated with. The error message when an instanced personal fails now includes the instance.
