QUICK QUESTION

I am trying to figure out how to store some of the lengthy multi-part essays I have posted online so that folks can access them easily. The UNC help desk told me about DropBox. Does anyone know anything about it? Is it safe? I don't need something secure -- I am happy to give the world access to the materials I store. I just want someone to be able easily to find my Autobiography, or my Formal Methods tutorial, or the Marx tutorial, etc etc. Suggestions?
