There are many toolbars you can download for your browser. One of the most helpful is Alexa. It is available from
www.alexa.com The search engine is powered by Google, the Net's #1 search engine. It also has related links on the bar. This can save you valuable search time.
One of my favorite features is the Site Info. Knowing who owns a site is important in evaluating information given on the site. Alexa even allows you to write a review of sites.
