"Obviously" they just need an email forward feature, but of course that would require admin effort for the kids that screw it up or intentionally create mail loops or mess with another kids account, so for CYA reasons that can't be done.
So the net effect is we've gone from a modest amount of paper correspondence to no correspondence at all because the tech doesn't work and nobody is interested enough in the message to fix it.
Another problem is for privacy reasons each kids email looks like "a java GUID"@something.k12.edu and nobody wants to use an address or username like that. ts impossible to remember their email addrs or passwords (they're written down on stickers on their devices) but I think it would be funny if its not "a java GUID" but actually their SS numbers run thru md5 or something even dumber from a security perspective.
As an adult, I have an email address like that from my cable company. I don't even know what my cable company email addrs is, much less its password. I've never used it and never will. God only knows how much marketing spam the cable co has sent to it. Maybe electronic bills too, who knows.
I think it's a false comparison to say it's like your cable address; a school has a multitude of good reasons for wanting to send email to its students. A cable company has mostly terrible reasons.
