The Friend Request feature works by sending out messages to the most active Friends first. If you receive a Friend Request you will see the message that the Member sent out. As a Friend you can only accept or decline the Friend Request. If you accept the Friend Request, the Member will be notified that you are interested in their Request. You can then respond to the Member by clicking on "Bookmarks" on the left side menu. After you click on "Bookmarks" you will see a "Friend Request" tab in the middle of the page. If you click that tab you will be able to see the Member and reply to them directly.
