How do I post a PDF to COTH forums?

How would I post a PDF to COTH forums? I know how to post a photo, by using Photobucket and linking to it. For a PDF I suppose I need to use something like Dropbox?

Try Scribd.com

First, Scribd seems to want my credit card before it will give me a free trial. Second it doesn’t seem like it lets you post things, just download?

You need to upload it somewhere whether that’s personal webspace or some kind of service and then post a link. A dropbox folder would work okay.

Scribd is free for uploading PDF documents. Their paid service is for reading particular books. You don’t need to give them a credit card just to upload documents.
