I had a great idea, not just one stock market but many, each one named after a tier. Ubers is the highest to LC the lowest. At the end of each month the highest group goes up one tier while, the lowest goes down. For example TPR suddenly goes on a downward spiral, and is the lowest group it would go down from Ubers (the current market) to OU. Let's say my group PPN does well in OU it would take TPR spot in Ubers. If a group in LC goes down the next group on the waiting list would take its spot in LC. This is good because it allows more groups to be advertised.
