Hey guys, I'm in my senior year in chemical engineering, and I am involved in several group projects. During the course of a project, we email project files all over the place, making it hard to figure out who's got what file and if files are updated. Is there an easy (and free) way to create a small online file repository for our group that can be password protected? I need to have the ability for my group members to download, upload, and delete files in the repository as we work on a project. I have 100MB of available space on my university server for a web page, but don't know how to program anything fancy. Any suggestions?
