I'm using MarketPress. I need more control over the categories and sub-categories. What I would like to make them global with edit privilege restricted to me. I saw on the forum several suggesting that were a couple of years old. They seem to be quite evolved. what I am hope is you have something more out of the box. If not, I'm good with a brute force. That is hard code the categories to a select list or do direct edits to the db.
Did I mention that this is a multi site which enables businesses to create their own store front. That is what is driving the need.
Any help would be appreciated.
