Skype, as well as Zoom, has come to the rescue for a lot of us allowing us to carry on with work and stay in touch with family, friends and colleagues. I was having a chat with someone on Skype and they wanted to know how I did it without having their Skype username. That's because I set it up as a meeting. This can save having to get other Skype usernames and also stop your address book from filling up. It also means that the other person(s) don't have your Skype username so they can't just call you, assuming you don't want them to.
