Just a suggestion. All PLAYERS. Add a number like player1, player2, etc. or add your name like playerabbi, playerjoe, playersam etc.
On your upper ;left corner there is an avitar and your level. If you click on this you will be able to choose an avatar of your choice.
I have four friends with the user name of player. if I overlook the ID when I receive a gift from one of them, it makes it difficult to know which one to send a gift to.
Using these suggestions will make it easier not only for me, but others who have more than on Player.
