Hi Rick -

Try using this url: http://cgi6.ebay.com/ws/eBayISAPI.dll?ViewSellersOtherItems&include=0&userid=old_moldy&sort=3&rows=25&since=-1&rd=1

I think you had a pointer to your "My eBay" page and the eBay server was substituting the user-id from the cookie files on everyones computer. So for registered users it took them to their "My eBay" and for those without a cookie it took them to the sign-on screen.
