For example, I might want to offer things like "1000 coins to the first player who joins my team and plays 10 team duels with me," or "100 coins to the first 100 people who score at least 10,000 points on one of my maps." The community page would have a searchable list of the published missions, and there would be a mechanism to transfer the coins on completion and de-list the mission after it's been completely paid out. This would solve two problems: it would make the game coins much more useful and desirable, and it would give us a way to incentivize social activities like team duels or playing our user created maps.
