Skype video chat rooms
Everyone knows what it means to "skype"—it's the modern verb for internet phone calls and video conferencing, all on the cheap (sometimes even when you're not using the Skype service itself).
No matter the mobile or desktop OS you use, there's a version of Skype that can connect you to friends, loved ones, and business associates far and wide.
To show only the people you like best, favorite them.
Or just disable the sound and screen on the "stealth" laptop so it doesn't give you away.
If you've got an external webcam, place it somewhere away from the laptop to still keep an eye on things—you'll just need a long USB cable.
You can edit the messages you've sent via Skype chat after they've been sent, Slack-style.
Just right-click on the message, select Edit Message, and you can change it. Hit the up arrow key to jump right to the last message for editing.
Advanced, you'll be able to set up the hot keys you want.
