Hi,
I'm trying to do this also. I beleive you need to change the category ID and then choose to put it in ID order on the general settings page. However I can't quite see how to change this ID (if you can at all?). Just went through all meuns and can't find it, so if someone can let us know, it would be greatly appreciated. (have searched on the forum, but can't find an answer).
Cheers
Mike
PS it could be that the cat id is created in the order you created the categories, so seems strange that you haven't got an option to alter the order?
