Hello, I'm David McMurrey, maintainer of the Online Technical Writing textbook.
I'm writing to tell you that I have had to move the textbook to https://mcmassociates.io/textbook/
The textbook at https://www.prismnet.com/~hcexres/textbook will no longer be available.
I want to mention that I have set up an online training shop for advanced technical writing courses at https://mcmassociates.io/
Come take a look!
