I have written a simple "games waiting" notification application for the Mac (Leopard and above). It displays an icon in the status bar with the number of games. It is available on my website:
There are similar applications available for Windows, and Linux I believe, but I could not find any for the Mac so I decided to write my own.
The application uses the gameswaitingcount_xml.php interface to the site. Refresh interval is initially 1 minute, backing off to to 30 minutes when idle.
Russ, I sent a message about this a few months ago. If there are any problems with this application being released please let me know.
I hope this will be of some use to people. Any feedback will be appreciated. At the moment the app only supports the main redhotpawn.com site but I will add support for the other sites if there is demand.
