I've decided to expand my support work and create a site where Veterans can receive free computer help (VeteransHelp.org). I'm using OSTicket (osticket.com) for the ticket reporting. What It really need is an easy to use desktop sharing system. In the past I've used TeamViewer because it is easy to use but it is not really free for non personal use. Recently I switched to Meraki Systems Manager because it is free and it uses VNC but unfortunately it isn't intended for the one-time-use type support I'll be offering. So I'm looking for a reliable, open source, easy to use desktop sharing solution that I can set up on my site for people to join one-time-use help desk sessions."
