This ensures that no \u2018person in the middle\u2019 is reading along.\n\nWe at [hsmr] and MaZe are using the opportunity that many of us are present at the same time to verify each other. However, all other creatures are also welcome to join. We are happy to help if this is your first time hearing about contact verification.\n",
