I'd like to keep my members up-to-date about events taking place within my group or out in the world. How can I do this?
You can manage an event calendar easily using the Events module. For information on setting this up, please see: http://www.groups-corp.com/wiki/item/using-the-events-module
What if my members don't check the calendar -- how can I let them all know about something important that's coming up?
You can send an email to all of your users by using the ‘group message' feature; access this via your administration module.
I've invited everyone I know to join my group, but can my group's members invite more people so that my group will expand even further?
Yes, your group's members can invite others to join by utilizing the ‘Invite People!' feature under the ‘My Account' link.
Can I change the date of an event after I've posted it?
Yes, you can; and you can use the group message function to notify your members of updates!!
