email notification based on status or ratio

[fatimon]

Hi

Would any coder out there be willing to make a version of the e-Mail Notification script that will send mail not when the download has reached 100% but when it has reached a given ratio value or when it has switched to "Stopped" status?

Thanks

I believe Growl on Mac can do this.

Well... I'm on Linux so Growl won't be of much help ...

The script author has been kind enough to send me a version that will send the notification mail only when status has switched to "Stopped".
That guy rocks

Here it is in case someone else is interested.
