<a href="http://www.tcs.org">Same Browser Window</a>
will cause a link to the Tulsa Computer Society site, in the same browser window.
<a href="http://www.tcs.org" target=body>New Browser Window</a>
Will also link to the Tulsa Computer Society website, but in a new browser window. The only difference is the addition of "target=body" in the "a href" tag.
I don't know about you, but I hate websites that open new windows for all of their links, because it is such a pain to have to close them when you are finished, and especially if you have to go down several levels, to find the information you want, because you must close all of the intermediate levels when you are finished, rather than just clicking on the Go Menu (in Netscape) or the Down Triangle (in IE5), and selecting the page you want to jump back to.
