Can the M5 be shared among a group of individuals?

We highly discourage this for multiple reasons. First, we would consider this stealing, as it is priced for individual use and would constitute a breach of our internet handshake to use it for personal use only. Second, your personal information can be accessed by any user with your username and password. Finally, tracking which sections you have done poorly on and need more work would be impossible, as all users would contribute to the results.
