Well this made things a lot easier! Histoplasmosis sent us a link which shows you how to do tabbed browsing on your Opera Wii browser. It is extremely simple actually! All you do is open up your Wii browser, and visit the address http://team-dsx.net/ds/basic.php. Once you go there, a little tab will pop up in your browser. You click the image to the left, which allows you to open new tabs. Awesome find, I just added this to my favorites!
