Adding a rating

If you want to compete for points, you need to add each other as friends.

Of course, in the future, you will add competitions with random people, but for now, it will probably only be with friends.

And you'll need to make it possible to add different avatars for each participant, or make sure that names don't get repeated.

Because you'll need to find your friends somehow.

If there are many different names, it will be almost impossible to find a person because the avatars will be the same.
