hearts ratings bug fix, list of tables bug fix

There was a bug in the update to the Hearts ratings last week which caused the losing players to get more points deducted from their Elo ratings than they should have. My apologies, I know some of you take the ratings very seriously!

I've applied a fix to the problem this morning. Anyone who would like to get their Elo ratings set back to where they were last Wednesday need only write to me and ask (marya@worldofcardgames.com). To do this, just make sure that you send me the email from the address that you registered with, so I know it's you. I will do this for people up until the end of November.

[Edit on Nov 24 2015: Only a small number of requests to reset Elo ratings have come in. After receiving negative feedback on the way this was being done, I decided to just go ahead and do the work to perform a bulk update of Elo ratings. Anyone who played at a ranked table prior to Nov 17 has had their Elo rating reset to the value from Nov 11, before the bug was introduced. To be clear, this was only done if it led to an increase in their ratings - I did not reset values that were lower.]

I've written a page about how the Elo ratings are computed at World of Card Games, so you can always check for yourself to make sure you are getting the correct results.

I've also applied a fix for the "list of tables", which had a bug that caused the list to stop updating. Third times the charm? I hope so!
