Join.me is a free online service that allows you to share your desktop with anyone. There is no registration required and the service works great across MAC, PC and mobile devices. All that you need to do is go to www.join.me and click on â€˜Shareâ€™. A small 1MB plug-in is downloaded to your machine and once you install it, it launches a small server on your desktop, which gives you a 9-digit access code. Share the code with the person who you want to provide access to your desktop. To see your desktop, the other person needs to open the join.me website and enter the code in the text box next to the sign that says â€˜Joinâ€™. It will take a minute or two to connect and will show your desktop in his browser window. You can also chat with the other person and share control of your desktop with him/her through the server.
