||I'm not quite sure I understand your point here..
How does "Writing name /handle on submission folder & in readme" affect the final score/leaderboard?
As I said above, finding which submission belongs to which member is EXTREMELY easy! Check here an example: http://take.ms/6sR8m
I'm reviewing that challenge right now.. I can find the submitter's handle from:
1) TC API
2) Video (youtube, monosnap etc) account.
3) Email on git patch(es)
If a reviewer makes exceptions based on who submitted, remove him/her from the review board!
