How do I view the pending friend requests I've made?

Unfortunately, a list of pending friend requests is not available. You can, however, determine the status of your friend request with another user when you find them in search. The "Add as Friend" link will appear if you have no pending friend request with them. If you have a pending request with them, "Friend requested" will appear instead. If the "Remove friend" link appears, you two have confirmed your friendship.
