Drop.io: If you need to share files, including pictures and videos, this Web site makes it a breeze. Just create a name for a "drop," upload your files to it, and then give access to anyone you want to be able to download them. Each drop includes thumbnails of the files you upload, so people can preview them before downloading.

5min: Want to get advice on using your iPhone effectively, or on asking your boss for a raise? Or maybe you'd prefer to leave work behind a bit and learn how to play the bass, or how to master the Pilates abs core workout routine.

The site is sometimes confusing to use, but it's very powerful once you get accustomed to it.
