Turn off annoying iCal invite replies

Many people have complained about Apple really ruining iCal. I won't go into the depths of that. A month after I moved to a new Mac, I discovered yet another thing that wasn't properly restored from my previous system - the plugin to disable automatic replies to invitations.

iCal.app automatically sends and Accepted or Rejected email for calendar invitations. I want control over this notification, but there is none.

Enter John Maisey's extremely useful iCal Reply Checker. It took me a while to search for this utility - it is hidden in a deep corner of the web. Anyway, I am delighted that I found this utility again and installed it promptly!
