Just noticed this on Wikipedia. pterry was always one for the grand - self-deprecating - gesture.
"Pratchett's daughter, the writer Rhianna Pratchett, is the custodian of the Discworld franchise. She said she had no plans to publish her father's unfinished work or continue the Discworld series. - - -Pratchett told Neil Gaiman that anything that he had been working on at the time of his death should be destroyed by a steamroller. On 25 August 2017, Wilkins fulfilled this wish by crushing Pratchett's hard drive under a steamroller at the Great Dorset Steam Fair.
Just re-starting this thread. I thought that it was time.
If you want to do something concrete in pterry's memory, in addition to pushing his books and perspectives, don't forget the Orangutan Foundation International. He was a big time supporter and advocate.
