help please

Hi Thelaus,

To add a friend to your friends list, press the Social button (the small icon in the upper left corner of your chat window), open the Friends tab, and left-click on the Add Friend button. Type in the name of your friend in the window. It will list your friend's name, where they are located, their level, and their character class. To remove a friend from your friends list, select the name from the list and left-click on the Remove Friend button.

There are other ways to add friends but these are the basics. Hope this helps! =)
