For views, how do I display only one of a series with the same title?
To only show one immediate next upcoming event: 


add Sort criteria by date (ascending so you get the events that are soonest to happen as first on the list), make sure the correct one come up top
and then limit your results to only show 1 row (Display a specified number of items to 1 under Pager options, but don't output the Pager).
