Keep track of number of users "recruited" by a user

Jan 15, 2008 at 4:44 PM
I am trying to build my first facebook app and I need to keep track of how many people a user has "recruited" by sending them an invite and they successfully add the app. I'm not sure where in the process I can save that info into the database. Can I still use the Multi friend selector (page or fbml tag)?
Thanks in advance...
