How to view Friend Requests
To view your incoming friend requests, visit your User Dashboard -> Friends -> Friend Requests. Here, you can choose to "Accept" or "Ignore" any incoming Friend Requests. Additionally, you can choose to "Accept All Requests" or "Ignore All Requests" by clicking the buttons at the top of your Friend Requests.
Note that ignoring a Friend Request will not send the user a notification stating that you have ignored their request.
How to send a Friend Request
To send a Friend Request to a user, visit the user's profile page. On the top of their profile, there should be an "Add Friend" button, clicking this will send a Friend Request to that user.
Once a request has been made by either user, you should see a "Pending..." button displayed on the user's profile, indicating that the user who received the Friend Request will need to Accept or Ignore the request.
