I seem to remember GGMB from many moons ago. I was also part of the messageboard that Int'l Gymnast magazine had. Not sure why that was ever shut down. Currently, my only other ones are the reddit mentioned above, and Gymnaverse, which seems to cater more to the fan than gymnastics families (so, people like me). I'm mostly watching NCAA these days. With Tokyo threatened to be cancelled, I can't even remember how US team selection is supposed to be done. All the info I see is on teams qualifying, not who will make those teams. Lame covid.
