Please go to https://www.dropbox.com/ and make an account. Then make a folder with your name “last first” and share it with me at email@example.com. This is where your work goes.
I will make a class folder for sharing general class materials as well. By keeping them separate (you ‘own’ your folder / I ‘own’ the class folder) we should be able to keep you from using all your storage with other peoples files.
