A few people had said to me that there facebook will add email addresses to there linked contacts. I have looked through all the options and do not see this anywhere and have checked to see if they have email addresses listed on fb.
I am pretty sure everyone is going to come back and say it doesn't do this, but if it does what the **** is wrong with mine!
Thanks alot, i do believe its possible it uses the emails you have as well, I believe i had one freind found and the only possible way was due to email. I could be wrong.
