WorkHappy, a great blog with resources for entrepreneurs, gives a four-star rating to MediaFire, a free web application that hosts those large files you might not want to email. According to the review, "The interface is near-perfect. No signups required, no maximum file size to worry about, and a host of simple delivery options when you're done uploading." Especially for designers and the like, this could be a good resource the next time you need to send a large file to a client.
