If you wish to be notified when this site changes, you have a couple of options.
The best way is to use a piece of software called an aggregator, which will display headlines and summaries for this site (and many of others of your choice). There are lots of choices, but I’d probably suggest starting at NewsGator. They have a nice web based aggregator and have bought into the (arguably) best aggregator applications for both Mac OS X (NetNewsWire) and Windows (FeedDemon).
Once you have an aggregator installed, you should be able to subscribe to the feed version of this site by clicking the logo below.

If you would prefer to just get an email, a company called FeedBlitz provides a service which will email you whenever new posts are added. You can sign up for this service by entering you email address below.
