Tips:
-Some e-mail accounts call for an extra step to import your Contacts into Facebook. Gmail Contacts, for instance, must be exported to a CSV data and posted to Facebook. The Find Friends wizard will offer on-screen guidelines if you have to take extra steps.
-Facebook claims that it does not store your e-mail password. It is just used to access your account in order to import your Contacts right into Facebook.
