adding friends?

just wanna now how can i add friends in the game?

1.) Click on the persons name and choose the option "add as friend"
2.) Use the console, type "/addfriend PLAYERSNAME" (without "s)

Latter code might differ from language to language, in German it's "/freundhinzu".

what s the button on my keyboard to enter the console?

Sorry, not the console. Just type it in any chat window.

thanks!
