I am having some students delete other students’ work. Is there a way each student could create a CoSpace, and then merge these CoSpaces into one when they are all done with their work? Is there a way to go back and see what student has edited what Space (like in a Google Doc)? Are there any other suggestions for the problems I am having? Thanks!
Right now, it’s not possible to merge several CoSpaces into one, but we’re taking this feature request into consideration 
In general going forward, you can check the version history of the group assignment to try and find the version you’re looking for, but it likely won’t be helpful in this instance, as every 7 minutes the system checks the difference between the current assignment state and the last stored version.
Sorry about that, but thanks for sharing your needs which gives us ideas and features to think about adding to improve CoSpaces in the future!
