Do you know people who still email you chain mail?

I have a family member who would constantly send me chain mail. This person was the reason one of my computers got trashed and I had to spend money to get it fixed. Even then it never ran the same again.
Even after I requested they not send chain mail. So I blocked them from my email. I have virus protection up the yahoo, but there is that occassional virus that can’t be detected because its new.
Do you know someone who still believes that whole thing about if you don’t send this email, something horrible will happen? Or if you send it to 10 people in 10 days you will suddenly be rich.
My favorite, is send this prayer link to 10 people for our soldiers and show your support.
Don’t people realize this is a great way to send viruses, spam, spy ware, trojans,etc.?
