|Hmmm...you must have missed the 3 spots on that page that include the word "download".|
Let me help you out:
1 - There's a small Download tab under the Search field found in the upper right of the page.
2 - There are the words available for download under the heading OpenOffice.org 3.2.1 under the tabs. Those words are a link to the download page.
3 - And then of course there's the big giant letters on the left hand side that read:
"I want to download OpenOffice.org"
Those words are also a link to the download page.
