Onboarded my 12yo niece to @delta yesterday. They were looking for a solution to chat with her peer group split between iOS and Android, many of whom don't have sim cards in their devices (+ parents rightly resistant to use big social apps).
We installed and were chatting within 2 minutes, with hardly a mention that this is going on over email (good thing IMO). Now their challenge is to spread it to the others in the group
Great work #FOSS projects meeting people where they are!
