how do you add friends!?!?!?! can you not search for them

There are two ways.
1,Play a game with them.
2,Go to their profile and click "+Friend" button.

To search players, you could install the appropriate things from https://www.warlight.net/Forum/106092-mulis-userscript-tidy-up-dashboard, go to multiplayer, click on search, type player name, make sure that all players are being searched then press enter on your keyboard.
