[LON-CAPA-users] Using Slots - Problem Due Date and Time Limit parameters

The ability to set both a start date/time and end date/time for  
reserving a particular "student-schedulable" slot will be available in  
the next LON-CAPA release (2.11).

In LON-CAPA 2.10 and earlier versions supporting slot reservations by  
students, only the start date/time for reservations could be set (the  
end date/time for reservation would implicitly be the same as the  
date/time the slot opens).
