There's a bug in the Dropbox program.  When too many people are trying to upload files at the same time, Dropbox gives you a message telling you to spend ten dollars for more space. DO NOT SPEND ANY MONEY. Just try uploading later.  If you still can't upload your video by 8:30pm, email me at [email protected], and I'll tell you what to do. I did warn all of my classes about this.  Remember when I used the 405 freeway analogy? Well, continuing that same analogy, it's rush hour on Friday, and there's a ton of traffic. You had over two months for this project.
