Passport Advantage is so incredibly bad it should be completely thrown out. Create a new site. Here's an idea, use Lotus Notes to build it so the Search actually works!
Availability of the Latest version of the software should only be a login, a search and 1 click away. (I'd love to skip the login, but if you must, you must)
If IBM insists on keeping that terrible site that's fine. Create an additional site one that is just for Lotus brand products. I'm certain somebody could do it in 7 hours or less.
Tell the legal people they will have to be satisfied with the clause "By downloading this you agree to the Terms" and offer a link to the terms. Nothing more.
I quite like the latest version of the Lotus Products. Too bad most folks can't even find them.
