Show creation date for sessions

When I see a session that's starts soon and has no interest, it may be possible that: 1. the start date was set too early and didn't have proper time to gain interest. I think a low-interest soon-to-start session doesn't attract as much clicks, but if it was visible that it was hastily created, it may be slightly more attractive. 2. the start date was appropriately long but there's really no interest at all. In this case the visible date might actually discourage people, but it already had no interest up to this point anyway.
