It is possible to set maximum participants per club - this is the maximum students per each club session, not anyone who has attendance the club at any point.
However it is not possible to specify a maximum number of clubs that an individual student can be signed up for.
You may wish to use Custom Groups to manage who can sign up to clubs:
- Set up a custom group for students that have not yet reached their maximum.
- Add automatic criteria based on the students names of those who have reached their limit.
- Your custom group will then contain everyone except for these students.
- You can then set this group as the eligible group when setting up new clubs - students not in this group (the ones who have already reached the maximum) cannot sign up.
