Chad Kafka presented on putting PDF files on a wiki. To create a PDF from another file format like DOC or PPT, one selects "Print" from the File menu, chooses "Adobe PDF 9.0" as the printer, and prints to save as a PDF file. Then in wiki edit mode, one uploads the PDF by clicking "File" on the editor bar, navigating to the PDF file, and clicking to upload it. The uploaded PDF will appear on the wiki page.
