Digitalfire will shut down on June 26. I no longer have the authority to grant exemption to a section in the Terms and Conditions of using material in the Insight-Live account from which I built the source material. While there are ways to comply with the take-down order, they are beyond my means because of how complex and large the site has become in the past 35+ years. It has been a wild ride for a shy prairie boy, thanks to everyone for your support. Insight-live.com is not affected by this.
