Explain and Send (Chrome Extension)

Explain and Send is a really cool extension to your Chrome browser that allows you  \to snag any part of a web page, annotate it, and send it to someone. It's like the application "snag it" but you have to pay for "snag it," and Explain and Send is free and I think a lot easier to use.  Once you capture the image or part of the web page you want, you are prompted to save it as an image, to copy it to your clipboard, or to share the link.  I found this on Richard Byrne's blog, Free Technology for Teachers.
