Digital footprint presentations

I liked all of the presentations, they were very good. I didn't know that it mattered if I had more than one username. I also didn't know that you could loose a job for having a Facebook or other social networks. I don't think it is right for a coach or a teacher to make students give them their usernames and passwords. People should think before they post things on the Internet. People should also make sure that they don't tell anybody their passwords or usernames.
