I'm happy to send it to you and you can host it from your dropbox if you wish. I'll continue to one-off email it to those that request it. Zero and I collaborated for a week getting this project done and instruction manual authored and I was told it will be hung on their website, so I can't envision any issues with hanging it on the wiki.
I just went through the setup process and you can now upload the following file types:
png, gif, jpg, jpeg, pdf, ppt, jp2, webp, doc, docx, xls, xlsx.
To upload a file, look to the left side of the site, and "upload file" should be under tools.
This also lets you upload images for diagrams and such.
I will eventually make it so you can embed and show the PDF on the page without downloading it, but that takes more setup time and I am currently at work.
