This sounds like the perfect alternative to creating Telegram/Slack/Discord channels just for simple communication updates, especially if it's with gamer friends that I don't want to know my real email address.
Two thumbs way way up from me.
This inspired me to start building Little Planets. It's a way to spin up your own hyper-local, hyper-focused social network with a single click. No fuss, no accounts required from anyone. I'm super excited about it. Just launching the beta today.
