I wanted to see the player’s profile. But I can’t find him by name in the search. Since he is not online now.
ability to search for players and view profile
You can search by player name in the FAF client's replay vault, and then click on a game that the player was in. Then, right click the player's name, and a drop-down menu should appear with the option for you to view the player's profile.
FWIW, I think they really should re-add the old leaderboards tab to the client, which allowed easier access to player rating information, among other things...
