Well this seems to be the MOST commonly asked question here in Time world.
So I will tell you how you add friends.
You can click on the player in the galaxy menu, and simply hit “Add friend” for the player you wish to add.
Or you can take the longer route.
-There is a little man silhouette bottom left of the chat box. When you click it a little box pops up that says “Friends” at the top of that box.
-At the bottom of the window that pops up there is an ADD FRIEND box that you can type in.
-Type the name of the person you wish to friend. Click “enter”
Now you know how to add friends. Please, if anyone asks, link them to this thread.
