| Secure communication is unfortunately still difficult for non-tech people. Most of the "easy" ones are tied to a smartphone, like Signal. However if the goal is to prevent accidental leaking by using reply-all or adding an email address by mistake, then I think encryption features are nice-to-haves rather than a must-have. It's a very nice to have, but for non-techies and for your specific use case, usability is probably more important at this point. I would thus recommend either: * Discord (https://discord.com/), easy group voice chat should you need one * Slack (https://slack.com/) using a free account, but they limit the number of messages for free accounts. May not be a deal-breaker for you. * Element (https://element.io/) which was formerly Riot.im, and is encrypted and have more security features vs. the other two. Probably the most secure here. All of them have their pluses and minuses, but all of them can be opened in a browser
and require no smartphone. I suggest you pick one that you feel is easiest for your group to register and use, and provides the feature set that you require. With regard to Discord, please make sure to read [0] before making any decisions :) [0] https://cybernews.com/privacy/discord-privacy-tips-that-you-... |
Discord roles are pretty messy for this though, to the point that secure conversations are often brought into a group chat or multiple separate servers.
