I have been an avid Insteon user since its inception and my interests began with the X-10 products years ago.  Needless to say, my home is completely controlled by Insteon devices.  Although a major inconvenience for me, I am not "dead-in-the-water" as I had purchased an ISY from Universal Devices several years back.  Due to the apparent shutdown of Insteon, I decided to dedicate a portion of my new website to host a user forum for those affected by the outage.  Feel free to share your workarounds if you have found an alternative, or ask questions of other members to get help.  Although my time is limited, I will post additional information about my ISY setup as I move forward with reconfiguration.  Thank you, Robert@GraspCast.
