Just to show I haven't been sitting on my hands for the last while, I HAVE been, albiet slowly, looking at the code to fix things. Next time I upgrade the server, these fixes should be implemented:

Moving cards can now no longer be done simultaniously between multiple users, in order to fix the corruption of the Store file.

A change in the points system - it will now be based on the following formula:
winner is 200+loser wins + (loser losses /5) to a max of 400
loser is 50 + (winner wins /2) + (winner losses /10) to a max of 200

The idea is that a) there will be a more 'sane' curve with less variation b) people who play on higher levels will get more points, and c) losses are still games, and should be treated as experience. if someone has a 100 losses, they'll most likely beat someone who hasn't played nearly as much, if they just played agains really good players.

There's also a few other things I can't remember.
