I considered using the multiple file option of the assignment task, and allow them to resubmit any number of new files (versions), but it seems that a better option might be to use the wiki and have history to show me the versions.
A couple of issues occur to me:
- Will I get notifications when they change things? And will this be too much, if they edit online?
- Is it possible to compare arbitrary versions of a page, like on mediawiki, or is it just two sequential versions?
- Can I take a snapshot on the due date, to be sure that assignments are properly characterized as on-time or late?
