Only 1/2 of the people receiving the invitation could join. It says 9 accepted but that's 9 invited. Many of us could not accept or go beyond this screen. So much trying and trying to make it work. A complete waste of time. And thanks for all the spam that you get once you make an account. I can see the invite but can't join or see who's joined. Below it says I'm not participating. All the clicks and trying never got it to work. And the admin had no luck either.
