The games are still there, but the ID number that appears at the end of the URL has changed. Alerts take you to the right game, links on a Group's home page work, and links in the vote chess search engine work. It's only links in the forums that seem to need updating.

All my three vote chess games give the message "This game has been aborted."
For reference, the games are (Kasparov vs. Karpov, Experienced vs. New players and Counterattack vs. Attack).
Should I have know this would happen? Will the games return in some time?
