The site has had a mobile friendly layout for many years
Back in the old days, a web site sometimes needed a special way to get to the mobile friendly version - which could be different from the "normal" siter. Not so anymore. Here, as well as many other places online, the mobile devices can just surf the same pages as everybody else, and the site will automatically reformat the pages to fit on the smaller screen.
A few pages and function - LeaderCalc in particular - will ot work well on a small screen like a cell phone. They can be shown, but it won't be pretty.
