I think we should consider a challenge rather than a contest. I think it would be really cool to see some of the skills that the players have rather than their talents outside the game (for a change).
For example, we can have a fastest map challenge in which competitors take a screenshot or video capture of their best time for a particular map. A specific example would be the "Dubai Hard" Time Challenge and any Dubai map played on hard would be valid.
The user would have to provide the date/EDT time stamp. I'm not sure if game data is stored on the server side...but if so, the Prole team could verify the accuracy of the claim.
To avoid spamming the system and making Prole work overtime, they can set a minimum result to enter. With the specific example I gave, the maps are 4:00 and the minimum entry point could be 2:00 (meaning that you have to finish the map under 2 min to enter)...
What do you think?
