Hi Bauble... I have a suggestion. Once you have a listing you like try using the template feature. it is the little pyramid looking thingy with a plus sign on the far right of the list of products. Go into manage products. It is on that screen.
If you do that you will have most of the info already filled in. Just change what you need to, add your new pics and done. Also, unlike most other web page editors, you dont have to hit save when you are done on the first tab. Personally, I fill what I need on the Product Info tab, hit the Secondary Images tab then I save it. I dont even use the other tab screens. I am sure Andrew and his lovely wife will let us know if we need those.
I have 21 listings up now. I do a couple each day. I find it easier than on HAF than on some other sites.
That is my three and half cents. Keep trying, you will get it.
