Use for coins

This really should have been posted in the General Discussion section.... At any rate I do think this is a good idea and would make coins actually worth something instead of just sitting and collecting dust!! They would probably have to set like weekly limits as to how many stars you can acquire or make higher conversion rates for the coins because lets face it you know they are not going to want people getting a ton of rainbow stars free of charge as that just takes away their potential profits they earn when people buy the stars.
