On Identi.ca there was both @KWLUG and !KWLUG - the user dents meeting announcements and live-dents the meetings, and the group is used for discussion amongst KWLUG members. It might be useful for all of @KWLUG's dent to go to the members of !KWLUG all the time, as well as have all the dents to !KWLUG go to @KWLUG, which it would anyway, since @KWLUG is subscribed to !KWLUG.
