Hi,
At our chrstmass party, i was showing a app I dev for kids and how I was going to use face book to help promaot it. My sisters husbands sister had face book send out a message saying you might like this for my app to all her facebook frineds. When I was on my facebook account, i had a message from her daying I might like this.

I'm trying to figure out how she did this.
