RFR - Ma edit reviews

You want to avoid pushing these keys to GitHub because there are nasty GitHub scrapers out there that will find them and try to charge you for things.

To get rid of them, do the following:
1.  Add `.env` to your `.gitignore` file.
2.  Regenerate your AWS key ID and secret access key on the AWS website.
3.  Add the new credentials to your `.env`.  

(Also share the credentials with the group.)
