I have sent an email to my brother who told me that he received it with a vcf
attachment.  When he opened it, and clicked on "Activities", there was a list
of all the emails he had sent to me.  He sent me a pasting of the screen
display to confirm it.  

I did not even know I could attach a vcf file.  How did this happen.  He
told me that everytime he receives an email from me there is the vcf file
attached.  This seem to be a recent occuring as he never noticed the vcf file
before. He was worried that someone else might get it too (if I send a
message to multiple recipients for example).

Would someone have some advice in that regard.  Many Thanks.
