Now here’s where using google drive is better than just any old file hosting. You can actually update the file that opens from the link you just copied. So if you make a new version of the rules, you can create a new pdf and replace the old one. Find the pdf you uploaded in drive, but don’t open it. Right click the file and click “Manage Versions”. A small window will pop up, and allow you to upload a new version of the file, and now when people open the link, they’ll get that version instead. Let me know in the comments if you have any other tricks for using Google Docs.
