I have used Skype very often and very successfully in the past.
We use Facetime to see our Daughter and Grandkids.
On Wednesday we used Zoom very successfully to hold a meeting of our U3A Ukulele Group.
This is the main system you see on the TV video clips, for private use it is free.
Simply Register on the website, (do make a written record of the details you use and do not allow the Computer to remember these details).
Then Download and install the App.
If you are holding the meeting click on hold and it gives you a Meeting Reference Number and a Password, pass these to the people who you want to join the meeting. At the appointed time start up the meeting and accept those who have asked to join.
To join a meeting, click on Join, enter the Meeting Reference Number and click to Join.
Then enter Password and wait for the host to accept you.
Chat away.
There are controls in Settings (gearwheel symbol) in the App to test out your Video and Audio before you join the meeting and once live you can turn on and off video and audio if required by a click on the icons at bottom left of the window.
For our U3A Ukulele Group we chatted and when ready to play we would all mute our sound so that the instructor took the lead, set the tempo and sang and we all played along and sang at our homes. We had to do it this way because there is a slight lag in speech and video which is not noticed when just talking but playing an instrument in time with others and the lag soon makes itself known.
