When lots of event dates are added to a post, it can look pretty terrible. To remedy this, I suggest that any event with more than three dates automatically stacks the dates, even in e-mail blasts. The logic would be very simple.
Another example from SFHS
Should logic be used to shorten the displayed dates on teasers? Or show only the next upcoming with an expand button to show all?
Anytime multiple dates are present, automatically stack in e-mail and on the site.
On teasers and in e-mails displaying in teaser mode, show only the next upcoming (with a label "next: ") and then an expand link to show more.
