A while ago, I asked about importing auctions lots created elsewhere. With CSV import it looks as if that feature is in the latest release. Great, but how do I use it? It would be useful to have a sample data record. Failing that, I think I can figure out most of it except for "category." How do I know what to put there? Also how do I handle images and items specifics?

I haven't tried this feature yet, but I'd start by doing a csv export. That should show you the structure.
