On most notifications, I see items like "Student X submitted an item to Assignment M".
However, I'm occasionally seeing notifications that indicate something like: "Student X, Student Y, and Student Z submitted an item to 2 other people".
Can anyone clarify what that means ("submitting an item to other people")? The only thing students should be doing is submitting assignments -- we have no discussions, tests, assessment, etc going on... I'm not sure if they're doing something they shouldn't be...(?)
I've googled this but can't find any info on this...
