Please review http://codex.wordpress.org/Function_Reference/wp_enqueue_script and update your plugin accordingly.

Keep in mind: Offloading the default jquery and other scripts to Google is similarly disallowed. If your code doesn't work with the built-in jQuery, it's most likely a noconflict issue. If you can't guess, we -really- want you to use our jquery, and if you can't, we need to know why so we can fix things for everyone.

You have the jQuery DatePicker code in your /skysa-required/ folder, and it's an older version that we have. Can you please switch to our version?

When you've corrected your code, reply to this email with the updated code attached, or provide a link to the new code.

1) Upgrades will not be done by your site. I know what you mean to say is that the code they're calling from your site will be maintained by you, and that's fine, but by saying upgrades, people think the plugin files will be upgrade, and that's not the case ;)

2) Along that same line, you need to be more clear about how the plugin runs code on your site. Just so people know exactly where their data goes etc.
