This page is not linked to from anywhere, so it shouldn't be indexed by search engines. Below are two documents I have linked in different ways. The first link is to a page that has a link to a file uploaded to Dropbox. The password is bfor1. The second page has a file hosted on Squarespace. The password is bfor2.
The advantage of hosting on Squarespace directly is that it just links to the file and doesn't show a third party interface like Dropbox. The upside to hosting on Dropbox is that if anyone wants to update the file, all you have to do is upload a new file with the same name to the Dropbox folder to replace the old one, and the file on the link is automatically updated. However, with direct files, you'd need to contact me to update the file on the website for you.
