Note: This application makes heavy use of <a target="_blank" href="http://www.w3schools.com/dhtml/">DHTML</a>
for its dynamic interfaces. It requires
a current browser that includes extensive <a target="_blank" href="http://www.w3.org/DOM/">W3C DOM</a> support.
It has been tested with the following browser versions:
</p>
<ul>
<li><a target="_blank" href="http://www.microsoft.com/windows/ie/default.asp">Microsoft Internet Explorer</a> Version 6+.</li>
<li><a target="_blank" href="http://www.mozilla.org/">Mozilla</a> or one of its <a target="_blank" href="http://www.mozilla.org/projects/distros.html">derivatives</a>:
<ul>
<li><a target="_blank" href="http://www.mozilla.org/">Firefox</a>: It's a whole new web.</li>
<li><a target="_blank" href="http://channels.netscape.com/ns/browsers/default.jsp">Netscape Navigator</a> Version 6+.</i>

</ul>
<p>
As of 2004, Safari, Opera, and others are not yet compliant enough to run GroupMind.
The browser requirement is not a whim of the programmers, but rather a consequence of the
use of Javascript, CSS, and the DOM. The functions required
by the application are simply not available in most other browsers. We expect this list to grow
as new versions of other browsers become more DHTML-compliant.
