Skype video chat rooms
Your Skype contacts list can get pretty big after people add you, you add people, or when you turn each number that calls you into a new contact.
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.
(You can also send a picture you've already taken, take a new pic to send, send your location, or send contacts in your list to that particular Skype contact.) Be sure to explicitly send the video after you stop recording, or you just recorded it for nothing.
There are lots of reasons to have multiple Skype accounts—one for work and one for play being the most obvious. With one launched, go to the command line (hit Windows Key R) and type either Calls, and check the box to "Answer incoming calls automatically" plus "Start my video automatically when I am in a call." Then, use that first Skype account to make a call to the second—instant video monitor on the scene to spy on the baby sitter, pets, kids, you name it.
One place you won't find Skype much anymore is smart TVs—you may still find it on older models, but after 2016 Microsoft pulled the plug on further development there.
Skype is always free to get, and free for calls between Skype users—you don't pay until you layer in extras, some of which are particularly powerful for business users.
