How would I upload a pdf and link it to a post on my homepage? Basically the PDF is a newsletter and every week I want to upload a pdf (newsletter) and have a link as a story on the home page. I'm using Drupal 7, is this possible? does a module exist for it?
You don't need a new module as this functionality is built into core. Go to (yoursite)/admin/structure/types and click "manage fields" for the content type you want to add your pdf's to. Add a new field whose field type is "File".
