Join.me is a dead simple scree sharing utility that lets you share your Windows or Mac desktop with other users. Just download and run a 1MB file and the app will give you a code that you can share with anyone. They can visit the join.me web site and enter the code to see your desktop, chat with you, call in to a conference line, or view a list of participants.
The service comes from the folks at LogMeIn, who have been cranking out excellent remote desktop software for the past few years. What makes join.me different from other LogMeIn apps is the ease of setup (it literally just takes a few seconds), and the fact that while you can show other participants your desktop, they can’t control your PC. This makes join.me a great tool for providing software demos or PowerPoint presentations, but it’s not going to let you login to your grandmother’s computer to fix problems.
