Caley took a bunch of pictures at her birthday party last week. She wants to share them with her friends. Which of the following choices is a low-risk way to do so?
1. using a password-protected website and making sure only specific friends can see it
2. posting them on an unsecured website that she knows her friends will visit
3. e-mailing them to a group e-mail list that includes her friends and a few others
4. posting the pictures on a social media site and tagging her friends
