You can create a different template for only the news section -- and that template would be the only one that contained archives, but the archive list (by months) would include every article/page on your site not just the news section.
So, no -- this is not possible.
A possible kludgy workaround would be to manually set your non-news article post dates to 2007. Then wrap your archives variable in a < div >. in this example the < div > would have an id=thearchives
Hey -- I said this was kludgy :-)
Then in your CSS you could hide the article list from 2007 like this:
#thearchives p.archivemonths + p.archivemonths { display:none; }
That bit of CSS would hide the second archivemonths paragraph after the #thearchive div. Of course, in 2009, this would hide the 2008 archives and you'd have to adjust the CSS again to hide the "third" p.archivemonths paragraph. Kludgy.
Sincerely,
Carl
