I can see your listings.

I can see your listings too under this ID you are posting with.

Ebay allows a member to change their User ID no more than once every 30 days.  This doesn't change the substance of your account, just the name.  Your Feedback, stats and listings all follow with the change.  However you have to allow for the system to recognize your change.  It you change your user name and then go try to see your listings immediately afterwards, things are not likely updated.  Ebay is a huge site and you need to allow for updating time.
