On this tab, you can see a list of friends whose friendship you requested. New friendships can be requested using the Add a friend link. You can cancel a request by clicking the Remove () icon or you can select more users using the check-boxes and click the Remove all selected friends link, which cancels more friendship requests at once.
Detailed information about the Friends module can be found in Developer's Guide -> Modules -> Friends.
