I'm going to temprorarily hijack this thread :)
Please think twice before making pdf's. pdf's are worse then html. Screenreaders cannot always handle pdf's since not all pdfs that contain text contain text, often they just contain images of the text. People with various reading problems (from simply needing reading glasses, to dyslexia) have no way to adapt a pdf to what they can read.
Thanks, I'll now step off my soapbox and let the debate rage on about the quarto mail.
