I agree that the ability to add PDF files would be useful. There are some procedures that might be better and easier shared without the risk of corruption by passing along as a PDF. I'm ASSuming that these documents would be somehow checked for malicious links??
> I work on a Wordpress website and I can add documents. I use Google Document Viewer format so everyone who has access can read it. On the wiki, we can add photos but not a PDF or other document. That would be a great addition. Someday!
