At the same time that you (we) are helping the devs at A/R design the best mobile racing sim, you can also help the dev at MAR design more features for the site - namely, Leaderboards, Challenges, and Tournaments.
For those of you not familiar with those features at MRR (looking at you Kahlipha), please have a look (top menu bar at MRR, then find the "About..." links on each page). If anything is still not clear, feel free to ask for clarification here.
Opening the floor for discussion...
