Quote - ... Hm, forum does not like the PDF file. Does anybody know if it is possible to attach a 691KB PDF?

Add a .txt extension to the pdf, so it looks like "MyDoc.pdf.txt" prior to uploading, and
tell everyone to remove the .txt extension.

That should work.

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.
