You can see it on the right side of most pages. There should be a "Start a Chat" or "Join chat" button there. Or you could go through the main bar at the top of the page. The chat is under the community tab.

Once you a regular on the chat (you can tell by their edit count when you click on their name on the chat), just ask if they have a link to the pdfs.
