I have been using this service for awhile now and I just thought I would formally recommend it. OpenDNS is usually a faster alternative to the default DNS provided by your ISP. It protects against phising automatically and can be adjusted to automatically block adult material aka porn. AND you can travel with your settings by creating an account.
Finally decided to find this one out. A good number of websites have little pictures next to their url in the address bar. For instance, Apple has a platinum Apple and CNN has the CNN logo. I finally decided to use MSN, MSN also has a cool webicon, to learn how to put one on my website.
