Submitted documents must be in PDF format only. Please search for free utilities to convert other formats to PDF. Avoid filenames with non-latin characters as this can cause problems with some browsers. It is best to use the upload submission method, but if the submission is over 10MB you can provide a hyperlink. This must be a direct link to the PDF ending in '.pdf'.
