CrossLoop is one of the best screen sharing software which you can use to provide tech support to your friends and family for free. Its easy to use by anyone.  Its safe , secure and the person who needs help can see all that is being done on his or her computer.

The connection only occurs when the person accepts it. The person who needs help basically provides the helper with randomly generated code an helper connects using that code.  I use it myself to help family and friends. Now you can register on their website and provide help to people all around the world and set your own rates. Get paid to help people.
