Someone thinks you're not very good at email.
They've sent you this link for one of the following reasons:
- They think you'll be too embarrassed if they said something to you directly.
- You've done the same silly thing more than once.
- They simply cannot be bothered with dealing with stupid people who refuse to learn how to communicate.
It's the 21st century. Email has been around for a little while now. It's a mandatory communication tool. It's a life skill, just like Googling. You need to know how to use email. You're functionally illiterate if you can't.
Your offence was:
BCC means STFU
... so don't embarrass me by replying to people.
The whole point of a blind carbon copy is that it's blind. In other words, I'm sending you a copy of this email but don't tell everyone that I'm sending it to you.
This is why you can't have nice things. And why your friends keep secrets from you.
