There are two primary scripting mailing lists on the Internet, one run by Apple and the other by Darmouth College.
Apple describes their list as follows: “The applescript-users list is for scripters writing scripts in AppleScript. It’s for everyone from newbies to experienced scripters, and it contains discussions on scripting style, how to script popular applications like Palm Desktop and AppleWorks, where to find obscure scripting additions, and ways to improve the performance and readability of your scripts.” You can subscribe here.
