When submitting papers, please take care in naming your files. Something like lastname_papersubject_year is a good way to name. classtitle_papersubject is not so great. paper1? Even worse.
It's not just about standing out from the crowd. I'd also like to be able to download student papers without potentially overwriting ones that have been named the same.
