I have another concern about the CJ feeds. WordPress has "tags" and "categories" The are often used somewhat interchangeably but they are clearly different things. When processing a datafeed, it would save a huge amount of time and effort later if you could somehow specify an existing category for all the items in that feed.
So far, nothing I've tried had been able to do this. After a feed from a vendor selling clothing, for instance, none of the new posts can be found in admin by using "Clothing" ad a category filter. Also, in the tag cloud and in the navigation for the site, clicking "Clothing" pulls up no posts except for ones that were either entered individually or edited to be included in the "Clothing" category.
This results in the site appearing to have no (or very few) products in the clothing category - very frustrating for users!
Any suggestions would be welcome.
