like that just change the "www.yoursitename.com" to the name of your site, and change "PDFurl.pdf" to the PDF documents URL.
oh yeah "click me!" is the writeing that shows up on the site
If you happened to have a pdf document named "grandpa-john.pdf" in the same folder as index.html, then in index.html you need this as a link to the pdf file:
If the pdf files were in a folder named pdfs, then a syntax like - Grandpa John is what you need.
Couple of tips. Since pdfs are often rather large documents you might want to include the file size info in the link, for example: Grandpa John [240kb]
Also, some of your visitors might not be expecting a pdf file when they click a link. A nice touch is to add a little Adobe pdf icon in the link, for example: Grandpa John
