Scheduler (plugin)

Hi,

I have few questions about the Attendance and Registration for Dimdim (if such features exists).
Consider this scenarios, with Moodle 1.9 and Dimdim Enterprise version.

On single course page, we have groups of students (as in a class with different sections).
The groups have dimdim based tutorials at said timings. (A student in one group SHOULD NOT enter the dimdim tutorial other than the one assigned assigned to him. For example: student A and B take tutorial at slot 1, and C and D at slot 2).

Is there a way to actually 'register' the students in the groups and control that the students of a certain group take the dimdim tutorial?

Also is there a way to check the attendance of the students? That is , did A and B took the tutorial at slot 1 or not ?

How can the scheduler module be helpful in solving the problem

I am open for any alternatives to handle the two issues.

Thanks.
A.
