schedules (i.e. term + school timetable) can't be dis-associated from sections

Could you suggest a user interface for this use case?

I need to confirm this.

Perhaps the term and timetable should be set when a section is created and then be clearly immutable. I'm just worried that allowing this to be changed would cause all kinds of insanity, like throwing off all the grades and attendance data associated with the section. We probably need a proposal to fix this.

I suppose that while you pretty much always would know what term a section applied to when you created it, you'd often create terms before you figured out when they met on the timetable.

During the Pycon2008 sprint the UI for deleting the timetables was added to the section timetable list.
