Twitch rolls out a private-message system called Whisper

Psst. We heard something about Twitch that you might enjoy. Lean in. A little closer. A little closer. Perfect: You can now send private messages to friends on Twitch, even if your buddies are watching different streams than you at the time. It's a feature called Whisper and it works by typing "/w" in a Twitch chat box, followed by the username you want to chat with. This creates a message that only you and your friend can see. For now, Whisper messages populate in the standard Twitch chat window and you can't set up private group messages, but the company is working to establish pop-out private messages and offline delivery. And, of course, you can block Whisper messages from certain users and dictate privacy preferences in Settings. See what those options look like below.
