Previous CiviCon events should be listed separately from upcoming ones
On https://civicrm.org/civicon I see two places which show lists (roughly speaking) of CiviCon events: (1) the slideshow and (2) the grey box titled "Upcoming CiviCon Events". I would expect that both of these "lists" contain only CiviCon events in the future. Currently I see St. Louis in both of those lists (which is a past CiviCon).
I would also expect that these lists are generated by views which do not require any manual content updating in order to hide previous events.
I think it'd be great to have a separate lists (further towards the bottom of the page) which shows the previous (perhaps five, perhaps all?) CiviCon events, and allows the user to click on each to learn more. But it's important that the user be able to quickly distinguish between previous and upcoming events.
