Hmmm.....let's see if I can help a bit. First, to add work to your portfolio, you go to your profile on the main EBSQ site, and on the menu to the left, click "artcase/portfolio". On the next screen click the "add" box on the bottom of the page. From there, you put in your descriptions and download the image files. When you finish adding the art, it will show up in your artcase. Beside it will be a dropdown menu. In that menu, you can "create a template" where you put in your auction description then copy the code it gives you to paste into the eBay auction description box.
To search for your art, go into "artcase/portfolio" again and key in one of the words of the title you are looking for in the bottom search box that comes up. The art should come up with the dropdown menu again.
Hope that helps some. If you are still confused, maybe you could be set up with a mentor? Good luck!
