Can't do this myself (yes I tried): Please remove the paragraph about dynfw on the page http://www.gentoo.org/main/en/projects.xml Please remove the list item and link about "Dynamic iptables firewalls" on page http://www.gentoo.org/doc/en/list.xml (Project is dead, pages have been removed.)
I've dropped the link from xml/htdocs/main/en/projects.xml. The link on the Documentation Listing page is about a former DeveloperWorks doc that already includes a disclaimer warning that the document is not actively maintained.
