Free online file hosting

I have a personal website that shares drama scripts. (Pop over and see us at www.dramatix.org) It's getting pretty big now, with more than 1200 scripts listed, so I'm running up against some storage problems, especially with larger pdf files. I think I've found the answer in MediaFire, a free online storage system, that allows me to store and then share a very large quantity of pics, pdf files, Word documents or whatever else I can think of. It has a very nice interface that is exceedingly simple to use, and there's a helpful video tutorial to get started. Recommended.
