I use DropBox daily as do many of my friends. It is brilliant for sharing files.

If you want to share a file you just have to out it in the public folder of dropbox and then get the url to send to the people you want to share with.

I can’t recommend it highly enough. Having 2GB of space for free is brilliant and getting upgraded to more is not expensive either. DropBox gets a thumbs up from me that’s for sure.
