Different combinations of times and rights can be set within a single ROPOT description.
For example: a teacher teaches three seminar groups on a different day each, and he/she wants to set up one ROPOT for all groups so that only students from a particular seminar group can always launch the ROPOT on the day the seminar group is taught.
For each seminar group, via the "Add another rights and time group" button, the teacher inserts a section within which he/she sets the right for the specific seminar group and sets the time when the student is allowed to launch the ROPOT session.
This way, the teacher doesn't have to set up three different ROPOTs, but just one.
1 Example of the use of rights and time groups – one seminar group will be able to work with the ROPOT on one day and another on a different one.
You can also add a special rights and time group. This option is mainly used to set up ROPOTs for students with special needs (typically used by Teiresias).
