How Facebook Suggests Friends
Action 1. Log in to Facebook and visit your good friend's timeline. Click the down-facing arrow with a gear symbol next to the "Message" switch.
Action 2. Select "Suggest Friends" from the drop-down list. Scroll with your friends to discover the one you wish to recommend, or get in the name right into the Search bar. Click the name to highlight it for sharing. You might choose multiple friends at once to suggest greater than one.
Step 3. Click "Send Suggestions" to send out the good friend idea. Both friends receive the idea under their friend Requests tab, which likewise tells them you made the pointer.
