Download full yahoo groups listing

Apr 2, 2011

I belong to many Yahoo support groups, many health related. When I go to

[ [title] ]

and log in to my account, the list only shows a partial list. That is until I scroll the page down, so it reads the next few groups I belong to. This continues for several more <page downs> until the actual full list is shown. I saved the complete HTML (including images and JS files) for both the initial displayed and the full list and the two HTML files were different sizes. How can I get the full list downloaded with TCC/TCMD?
