When having an events category, events should really have a double sort. First sorting by upcoming events versus past events, then sorting by event date. Example:
- Event 3 [in 2 hours]
- Event 4 [in 2 days]
- Event 1 [1 day ago]
- Event 2 [10 days ago]
The reason this is an issue is that the category then becomes cluttered at the top of the topic list with all of the old events that have passed, and users have to scroll down quite a bit to find the next upcoming event.
