Hi,
I realise that you have not yet released the API that was being talked about last year and am not sure if it will ever be done now.
However, would you be willing to release a list of the reference numbers you associate with categories?
I'm midway through writing an app. for Microsoft Windows to allow users to compare prices on auction sites. If there is to be no API a simple list of category references would be greatly appreciated as I would really like to include eBid amongst the results. It could drive more customers here so would be to your benefit.
