I've posted a new build for News Articles in the downloads section (members only).

New Functionality Includes:-

• Added [EMAIL] to the comment and article email notification tokens.
• The default template has been corrected for xhtml compliance.
• Added [HASCOMMENTS][/HASCOMMENTS] and [HASNOCOMMENTS][/HASNOCOMMENTS] to the comment.header.html and comment.footer.html templates.

Fixed Bugs Include:-

• When using [SUMMARY:XXX] or [TITLE:XXX], if the XXX parameter is not a number, it will no longer throw an exception.
• The article title will no longer optionally display the title of the article in the url (based on length). It will now always display the article title in the url.
  
• The comment notification email from unauthenticated users will now work with tokens such as [USERNAME], [DISPLAYNAME], etc.
• Links to articles, categories will now correctly append the language parameter to portals that have have it enabled.
• Navigating to the "create article" page when unauthenticated will no longer throw an error.
• The template.css link is now a valid xhtml tag.
• The pingback link is now a valid xhtml tag.
• All rating images should have transparent backgrounds.
• Breaks (
  ) in comments are now xhtml compliant (
  ).
• When applying a category filter, the syndication page will only show filtered categories.
• The link to show an author's articles will include the author's username in the url. (e.g. live example). 
• The template.css is now correctly loaded when launch links is set to true and you are on the view date archive, view author or view category pages.

Thanks again for your assistance.
