How to add friends with Flirt.
Select the Strangers Smart Folder on the sidebar.
Select people in the main window.
Either choose Add as Friend from the Facebook menu, or click on the contextual menu button that appears next to the persons name in the main window.
Choose Add as Friend.
The friend request window will display and you can add more recipients and optionally enter a message that will also be sent with your friend request.
If you are sending friend requests to multiple people, you may see this warning.
Click OK to send the first friend add immediately, the other requests will be added to your Friend Add Outbox and automatically sent and regular intervals according to your account preferences.
Click Send Now to see all the friend add requests immediately. This is not advised due to Facebook's strict limitations placed on friend adds. If you send too many friend add requests Facebook may temporarily disable your account.
Friend requests will not be sent to people that also exist in the black list folder (which also includes people that have a pending friend request). Selecting the Strangers guarantees that you will be sending friend requests to people that you haven't tried to send to before. Another useful strategy is to send friend requests to People You May Know.
