Gmail is the best webmail client out there. Finally, my inbox is organized thanks to threaded messages. The search is quick and works well (figures) and I'm able to track conversations much more easily than I ever have been able to before.
Always enjoyed the simplicity, and it's an online encyclopedia so I don't need to buy a whole set of books. It's possibly one of the most amazing sites on the Internet.
Roomster.com is a great site. This site helped me find a really affordable room to rent rather fast. The site is easy to navigate and there are no hidden fees or tricks that they use to get more money from you. They also have a ton of rooms available so I m sure there is something on the site for everybody.
