How does one add a friend?
I want to add a friend.
Click on your avatar, select "Friends" then "Add a Friend". In the filter box, type in the username of the friend you are looking for. It must be spelled the same way it is in thier username. When you see their name on the results list, select it and click "Send Friend Request".
Now you will have to wait for them to accept. Once they do, their name will show in your friends list and you will be able to invite them to custom match games.
