RSS feed links changed
The Internationalization Activity home page has recently been ported to WordPress. This means that the URIs for the various RSS feeds have changed. You can find the new links at the page W3C I18n news filters and RSS feeds.
The current URIs will continue to work for a short while, to support the transition, but you should change as soon as possible.
URIs for category filters have also changed, as have those for search key text within posts (useful for finding the history of a particular article or document). The latter have been converted to tags.
