Mike, awesome job on the archives! But I have a question, this seems like a bug. When I'm viewing a message in the archives, at the top of the page there's a "Date" link and a "Thread" link. I was expecting that when I click "Date", for example, that I'd go to a page showing posts sorted by date, but the date context would include the previously viewed post. For example, I was just looking at an email from Nov 1999; when I click "Date" I expected to see more emails in that timeframe, instead it went to the most recent posts.
