I've added a few features:
1) You can email articles to your friends. If you click on the little envelope at the end of any post, it will let you forward a link to anyone. I'm doing this blog for anyone who is interested, whether they are a student or not, so feel free to pass it along!
2) For those of you who speak Arabic or Spanish, I've added options to translate to those languages using the Google Translator. These will always appear in the sidebar to the right hand side of the page.
