Is there a limitation on the number of files a student can upload into the draft area using the advanced assignment feature?
I'm using 1.8, and there appears to be limit of 20 on mine. I'd never paid attention to it before as 20 seems a bit excessive, but then for my subject, I actually try to read each version. In any case, if someone is looking for a place to store all drafts or to track changes, I've tended to use the wiki for that purpose over the assignment. Hope this helps.
