I think everyone in the group text can see the numbers in the group, but they dont necessarily have to know who is who i guess. something like telegram would be perfect for this imo, but that requires downloading an app. signal and telegram can act like your normal sms messaging service, tied to your phone number, or used on the web.
I think the best messaging app is Jami, you dont need to provide any data to use it, you can just use it and it generates an ID for you (no email, number for an account, but tied to the device instance), but again it needs an app(phones and computers are supported!). It is completely anonymous, open source and has end to end encryption by default. Also its peer-to-peer so no server is holding your messaging data. Otherwise its like discord, slack, fb messenger. Pretty feature packed.
Reading this a year and another year of the pandemic later. I've been culling a lot from my library and related things and came across a new, unopened version of Pandemic, the board game. It's kinda like Sim City but a global pandemic. Two can play but better if four.
I never could get anyone interested in playing it, and even suggesting it is now probably gauche, at best. But it's free to anyone who wants to do a porch pickup at my house on the near east side of PA.
