Some bits of the old site were broke - for example the Java applets mysteriously stopped working for some users, myself included.
 
But it still could've been fixed short of rewriting Caissa from scratch. There were also some ideas that I had for the old site which I didn't get round to suggesting, such as optional JavaScript enhancements to the HTML game interface, which would have potentially tripled the speed of the game interface for those unable (or unwilling) to use the Java one.

The one and only fault on CaissaClassic is the possibility
"to abort game". I would like to hear Admin comment on this. Is it really a major technical problem to have this fixed ?
If you disconnect more than once in one game you have to deal with it
in such a way that your rating will change. Fair? I think so !

The rating does change, so long as the opponent doesn't click "abort game" but waits for the guy who disconnected to forfeit on time. Sounds fair to me.

What I really ment to say is I really dislike it when you've waited even twice in a row ( you chose to keep on waiting ) and you get the message "Game has been abotred" and the rating doesn't change at all.
You don't gain anything and your opponent who disconnected on purpose couple of times didn't lose anything. It seems to me that it is only worhwhile to wait if your opponent is not using Mars interface.
If both of you are using mars interface forget it!
