Charles, I don't mean this to be insulting, but if you know how to copy and paste, linking to your auctions is easy.

Go to your My eBay page and click on any one of your auction listings. Then click on "see other items." Then copy that URL (it should start with www.ebay.com). Then paste that URL into your chipboard post, either in the main text or in the space below where it says Optional Link URL. That will display all your auctions.

Good luck.
