Digitalfire is facing a takedown order from Plainsman Clays. They are revoking permission to "use any Plainsman content" "on any platform". This is broad and vague enough, and this site large enough, that I am unable to comply or even interpret it in the short timeframe (June 27). Please don't panic, I am overwhelmed by the unbelievable support I am getting. We just need to get them to relent on this demand and call off the lawyer (to at least permit commentary). There are lots of backup sites (many people have the API endpoints), don't start downloading or scraping again and overload the server.

Insight-live.com general operation is not affected by this.
