How do I place the latest announcements on my project home page?

You can use an RSS-2-javascript tool like http://rss-to-javascript.com/ to convert the RSS to javascript, which can then be added to the project’s index.html page. In such a service, you have the option to specify how many announcements must be listed in the project page. Setting this option to 1 will place the latest announcement on the project home page.
