.pdf in post

[ezdays]

You should be able to attach either a .doc or a .pdf directly as an attachment to your post, just as MasonJar described. You can also link to a .pdf if you have it located on another site. There is a maximum file size on attachments however, that being 250 Kb. PDF's usually cannot be resized, so if it's a file that larger than that, the best bet would be to either link to it off-site, or perhaps change each page into a .jpg and upload those.
