How to share stacks with a class of students

Here is one way you could distribute stacks to students in a class:

1. Teacher makes a set of cards using the Mac app, including images, audio, video and text (as needed).
   
2. Teacher selects stack, and chooses File > Export. Choose Studies Archive format (not StudyArch).
   
3. The exported file is put somewhere that can be downloaded from. Eg Dropbox.
   
4. Teacher creates a share link with Dropbox, and sends it to the students.
   
5. Students click the link, and the file downloads in Safari.
   
6. Student clicks action button, and chooses Open In…
   
7. Student chooses Studies to import.
