Each role may be played by one or by many users. Each role can only be played by users in the group specified below. If a group is not selected for any role, user in that group will not be cast in the simulation

TODO: (0.1h) Show total number of users per case

In Automatic casting, only users from these groups will be assigned to the roles. All user from all selected groups will be cast. If all users for one rol are cast before all users for another role are cast, you will b cast as many times as needed to fill out the cases. (You ca change casting assignments here.

In Group casting, users can choose which case to join Users are still restricted by group/role limits set below (e.g. if each case requires three users from group X and two from grou Y, the fourth user from group X to try to join will b rejected.).

In Open casting, users can choose which case and role t join, subject to the restrictions below

TODO: (0.5h) if enroll-type is open, show all groups from the subsite in each role

TODO: (2h) Make sure rule for checking each tab is correct

TODO: (3h) put a warning next to the finish button for any incomplete requirements, using the same tests we use to determine if tabs are complete. Should include: Warnings:

• missing attachments

• missing dates
• any invited or enrolled groups that aren't cast to any roles

TODO: B: finish button should appear on every tab

TODO: (8h) make sure that we are generating all of the notifications that we should:

• When a user is enrolled, if casting type is open or group, send a notification with a link to the casting page (on finish button)
• When a user is invited, send a link to the enrollment page (on finish button)
• When simulation notification date is reached, send an email saying that the simulation will start at date X. Include the description.
• When the simulation starts, send an email with a link to simplay with case_id
