A month or so ago, I tried making all of the archives resemble this main page, and ending up screwing up the code. So I’m being a little more cautious this time.
You will note that the individual archive entries are better this time. You can read the “email this to a friend” fields now (before they were black text on black), they include the proper author attribution and e-mail link, the comments area is now showing, and the page header is the same as on the home page.
