I downloaded the current trunk then I did a run -s and made a copy of the plist file. When I do a run I get this: ./run Usage: twistd [options] Options: -f, --config= Path to configuration file. [default: /etc/caldavd/caldavd.plist] --version --help Display this help and exit. -o, --option= Set an option to override a value in the config file. True, False, int, and float options are supported, as well as comma seperated lists. Only one option may be given for each --option flag, however multiple --option flags may be specified. /Users/jjkirby/documents/Darwin Calendar Server/Twisted/bin/twistd: Wrong number of arguments. Where am I being stupid? I'm running 10.5.1 Whether you think that you can, or that you can't, you are usually right. - Henry Ford
