Ooh that reminds me -- one of the classic annoyances we had with Mailman 2 was the difficulty of manually deleting messages from the archives. (You had to shut down part of the mail server to avoid conflicts, then manually overwrite part of a giant archive file to remove the offending message, *then* rebuild the HTML archive pages.... PAIN) If there's a handy way to remove things from the archives via the web interface or API now, I would just be so happy. :)
