Hi I do recall yes
And that schedule upload was how everybody expected Google to work from the first moment it was announced it was to be released!!!!
But they went with some crazy FTP idea instead.
The Froogle Feed V3 is designed for this exact method, where it produces an XML on a module, and you can write click "Copy shortcut" then paste that in the schedule, so Google visits this URL and collects the data.
Other shopping systems such as shopping.com and price runner work in this way, so everybody assumed this is how it would work here as well.
When it didn't, we had to then build V4 to have an auto upload feature.
You can see the V3 working to the right of this forum, just click on a link, and it will show you that feed
This could be the answer to a lot of queries, i have set one up on my Google account, to see if this works, ill let everybody know as soon as i know.
Regards
Ian
