Although the advertised cutoff for uploads was October 28, Yahoo did not actually manage to bring it off at the deadline (surprise?). New messages are continuing to appear on the web as recently as November 26. They are downloadable by PGO4 as well, so I'm taking incremental backups while I work out a solution.
Messages may continue to be stored at this time. We simply haven't had any activity in our group.
