> Please can everybody who doesn't upload PDF to the meeting materials page > at least take care to upload PPT instead of PPTX? As a chair, I convert PPT and PPTX to PDF first, and always upload the PDF. (And I ask participants to send me PDF in the first place.) Some people prefer to send PPT(X) because they want to do fancy animations. I try to discourage that, unless they can really make the case that the animations make things significantly clearer. So far, no one has even tried to convince me. Barry _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
