If we want to continue to use the same platform for the new years challenge this is one of the keys we want to go for, as it will allow us to differentiate between different years submissions.
As the challenge only has one set of submissions we can select all of the original years entries by grabbing those with an empty 'challenge' - or create a data migration that adds in a reference to the 2013 challenge to all existing challenges.

This is fairly easy to do in Django but for some reason I didn't do this - with this in place we can use the variable in https://github.com/mozilla/gameon/blob/master/gameon/settings/base.py#L14 to associate each new submission with a specific challenge.
