[LON-CAPA-users] Managing Time Slots - How to set the parameter "Period of time slot is unique"

[Amos Lee]

OK, I see.

Actually, I prefer the idea of requiring the course coordinator to first 
remove the student from the reserved slot which the student missed before 
that student is allowed to sign up for another still available slot.  Doing 
it the other way might send the wrong signal to students that it would be 
easy to reserve another slot if they missed their previously reserved 
slots--something we may not want to encourage.
