I live in a coop that requires member participation. It seems GR is turning into one too. I just got a message from one of my group coordinators. She said that she is doing purging of all the inactive members of the group. I'm inactive in that group discussions, that's true, I just write reviews. I guess I'm fated for expulsion out of that group. I'm not sure it's a bad thing but I don't like it anyway. "Expulsion" is such an ugly word. I suspect all the other groups will follow soon.
