I have just had the pleasure of my first online tutorial with a client using join.me, the new screen sharing service. It’s so easy to set up. Simply click on the link to join, and share the pin code with others. You can set up conference calls, and even give control of your pc to the user at the other end.
Not only did it let me do some tuition for my client on editing their website, but also allowed me to take control of their pc for a while to set up their email accounts for them.
There will be some concerns over security but so far this looks like the best tool for remote conferencing invented.
