Improvement request

Can be a useful and good module but not realistic yet, lacks several things:
I proceed with an example to make it clear

Start Date: 29 Nov. 2006 15:00
End Date: 29 Nov. 2006 16:00
Event length: 3 hours

An event usually needs several different roles, e.g. Anchorman, Speakers, Registrar, etc.
Each role needs it’s own time slot, e.g. Anchorman role needs time slot of 3 hours, from 15:00 to 16:00; First Speaker role needs time slot of 10 min.; Second Speaker role needs time slot of 5 min.; Registrar role needs time slot of one week before the start date.

Improvement Plan:
First we will give user ability to add unlimited time slots and edit or delete them for an event, when user creates a new time slot, we will ask for following fields for every “time slot”:

-Time slot name or Role description
-Length of time slot (can vary from min. to days, has start and end date and time. Can be before, during and after event)
-Number of volunteers in time slot.
-Volunteers
-Notes

This way the module will become useful for many people.

Best,
