Unfortunately what I've found is that anything that claims "high security" or P2P technology means that they don't support the ability to record all broadcasts on a central server. I understand and appreciate where those products are coming from, but education institutions have policies that require all communications to be reviewed and audited.
Really? I would of figured anything that claims to be "high security" was just making delusional marketing points and was the same bog standard security you would get elsewhere.
Why do you give snarky trolls like kevinxucs advice on how to avoid/circumvent the hellban? If you took the time to read his post history, you'd see he's exactly the kind of 1 line, trollish, thoughtless commenter that we don't want to see in HN.
