Before entering the El Nino Virtual Classroom make sure you have the right software to view this site properly. At least, you need Netscape 2.0 (Internet Explorer might work too) and the SHOCKWAVE for Director plug-in (available for Netscape and IE). If you don't have them, you can download them below.
When you've done that, click "ENTER"
Even without SOCKWAVE all of the site should work and be valuable.
