In the upper left-hand corner of the window that appears after you select a gift, you can write a message that will be sent to your friend together with the gift. A tick in the “show who needs it” check box allows you to see the players who added a certain material (the one that you are about to send as a gift) to their Wish List. The “Send to everyone” button allows you to send the same gift with the same message to all your friends at once. In the bottom part of the window, you can enter a friend’s name or nickname for a quick search.
