I guess(hope) this is the magic thread that we should post questions about the Rules?(posted 9606 days ago)- It is STRONGLY encouraged to include a screenshot of the game at the end of the game.
I think this should be forced or not mentioned at all, but not encouraged. Since it's harder work to make a screen shot if you forget to at play time or keep forgeting to do it at the end of a playback. Lucky people who have inps that always playback but don't give screenshots shouldn't be benefited for laziness by not puting a screenshot up.
