After a match in the score screen, you can start a chat with all players from that game. But if i close the score screen, I see no possibility to contact that players again.
In the Replay tab you can only start the replay or resume the game, but no way to get the statistics back.
How can I start a Chat with a player, that I played a match before?
Is there a hidden button to contact a player from a replay? Or maybe over Battlenet pages like this?
