manners and listservs

Paul G announced on the RASC Toronto Centre Yahoo!Group that he was going to bring a "special" guest with him to the Members Only event at the David Dunlap Observatory tomorrow night. His guest was the treasurer from the Montreal Centre. I thought it a little... odd. Technically, to be formal, one should ask first. Instead of telling? Of course we'd allow it. And this really didn't need to go to the whole group, to all members... More misuse of listserv group communication technology. He should have privately emailed Stu. Or the Ops group.
