Computer etiquette

So if you don't already know this I'm trying to inform as many people as I can.
When you send a mass email to all your friends, collegues or people you know.
Make certain that you Bcc them not CC them or put them in the To: slot. For those of you who aren't computer savvy let me clarify it.
Sometimes you need to send a mass email, we all hate getting them, but we know they are necessary evils.
This is how not to piss anyone off.
When you write this email only put your email address in the To: slot. And then put all your other friends in the Bcc: meaning Blind Carbon Copy slot; which is located under the Cc: slot (or Carbon Copied slot). In doing so you will not reveal everyone's email address to everyone else. Thus in doing so we will not get some rancid fucken chain letter or there is a boy in Bangor, Maine who is dying and wants to send an email around the fucken world email from your crazy or religious or superstious friend that you haven't seen since grade fucken 9.
Thank you.
