answer:You can post it on the group wall, and it will go out as a notification to all of the members instead of a message in their in-box. Our reunion coordinator sent out an Event Request with all of the information. If you are on the group page, look over on the right hand side, and you can see an icon to Create Event. Personally, this works out even better, as it will track those that accept or decline the offer. The event information goes into their Facebook calendar.
