If the series name field were an admin controlled dropdown list, staff could consistently select/name events as appropriate. No added keystroking and risk for creating incorrect series names. If it could be a multi-select dropdown list, it would also allow us to make an event part of more than one series when needed. Not sure how this would be handled on the public view. Maybe a quick display of matching series names with say 5 to 10 events for each series, allow the user to explore more in that series?
