Not a requirement, just a suggestion - packets uploaded to the question archive be uploaded as a series of individual .pdf files, as well as a .zip file containing .docx versions of all the packets. This year's NASAT is a good example: https://quizbowlpackets.com/3040/
The reasoning is that .pdf files are easier to open on computers and phones for reading purposes, and the .docx files are better for uploading to qbreader.
