Of course lynx cannot process frames. But that is not what I meant to tell you. Open the web page with your browser, FireFox, Chromium, whatever, the CTRL-U to display the source. In that source, you should see some tages <frame ir maybe <iframe which contains an URL. Copy that URL and try to paste it in a separate window of your web browser. You should see the list of the topic you can select from. In fact it should display the contents of the 1st frame. If it does not, you are in a not too good shape. If it works, go back to the source code and locate the second <frame tag, find the URL, copy, new window, paste. The concept is to access to the contens of the frames directly, without accessing the main page.
