"YOU ARE NOT ALLOWED TO EMAIL YOUR ASSIGNMENTS, ESPECIALLY cos111-u."
Well their helpdesk TOLD me to email it, so I have to trust that that is what I was supposed to do.
I don't understand why they have to manually delete the file, it is easy enough to do programatically, I've done such web applications where users can upload, delete, re-upload files etc, it really isn't rocket science.
Anyway, I've contacted the department and they say it shouldn't be a problem. But yeah, I've learnt my lol, don't cancel assignments on the day they are due hehe...
