My modest proposal was that FIRST "charter" a group to have FIRST teams. For example, the "chartering organization" might be a school, a company or a club of some sort (Boy Scouts, Explorers, 4H, parent's group). The chartering organization would be given a single number, and each team would be a branch off that. For example, Exothermic Robotics, FIRST Organization 575, would have FRC 575, FLL 575-L1, 575-L2, and FTC 575-T1, 575-T2, etc.
If FIRST wants to use this, I won't even charge royalties. (Especially since I stole the idea from Boy Scouts, where a chartering organization can have Pack 575, Troop 575, Crew 575, Ship 575, and Team 575. For example
