Still working like a dream. Thanks again.
It even served as an early warning system when the server (and therefore the streams) were down momentarily the other day.
One more question, sorry! Is it possible to put more than one of the XML feeds in a single Python script? Thereby giving more than one total in the notification balloon. Actually it would be great to be able to add the numbers of two feeds together and show the total.
However, if neither is possible I'm very happy with what I now have. My life is transformed!
