Some of you have written that by the time you receive the email update, the market has moved, or it is the next day. May I recommend that in addition to subscribing to the email updates, you also click on the RSS button at the top right corner of the home page? That will create a feed for you, and it is a convenient way to read the updates in a timely fashion. Once you have subscribed for the RSS Feed, be sure to modify the feed properties to automatically check for updates every hour. (In Internet Explorer, the feed will be found by clicking the star button on top left hand corner, and the feed properties link will be at the right hand bottom once you see your feed.)
If you need a detailed explanation about how to use the RSS feed to your benefit, simply search in Google about this. (Of course you didnt need me to tell you that!) Enjoy.
