I used to get them ALL the time, until I sent a multi-purpose email to EVERYONE in my address books on my emails telling them to PLEASE do not send me ANY type of chain letters, i do not believe in them, they take up space, some have viruses attached, and generally iritate the crap out of me. Everyone complied, except for one, who is now blocked off my list. If that person wants to email me, they can call me and explain why they keep sending me those stupid chain letters.
And BY THE WAY, any kind of chain letter, postal, email - regardless are ILLEGAL and a federal crime.
