Hello
When you create a event in a group, you can set the event field "Member Transfer Type" to "Invite" so that all group members are invited as guests.
But then group members don't get any notification that they were invited (they do when they are invited to an event outside of a group...).
Because of another issue I raised (
http://stackideas.com/forums/newly-created-event-does-not-appear-in-group-timeline-until-the-user-attends), this is getting very hard for the members of a closed group to be informed that a new event was created in group. Nothing in timeline, no notification... no chance that they ever attend!
.Fixed in ES 1.4.8
