As a teacher, I use a calendar and upcoming events block (may have the name wrong). I can post an event in a course calendar. Then decide if it should be displayed as a site, course, group or user event. I can set a window so only the next 21 days of events are shown. Past events are not show, but can be clicked on via a calendar block. There is some color codes associated with the site, course, group, user events.
Hope this helps. I hate to see 0 replies to older posts in forums
