Heck, Critor2000 is a teacher and he's the one who was involved the most in figuring out why TI-Boy SE, Emu8x, Omnicalc RAM Recovery/Virtual Calc and RealSound all crashed on newer 84+ calcs. He also tried to figure out why on certain calcs the LCD gets distorted when running some ASM games. He figured out many things about various calc models, even if some stuff isn't that useful (like the TI-73/76 Self-Test key combination). Plus he's nice in overall, unlike some other ppl in the community
