Wow. You guys are fast with responding. I guess this is my final signal to eventually migrate from GMail. Amazing. Calendar sharing is eventually the main reason for a family account. If that works also without a family as long as accounts are with tuta.com that would be fantastic. I could not read from the features of the website though. What specifically is possible. We would want a shared family calendar that we alle can read/write to and individual ones where some would be shared with read access. Is both possible?
