Selling Preferences isn't displaying in My Account

[doglover0026]

I am trying to setup a seller account. The problem is that the Selling Preferences in the Site Preferences isn't in My Account. Could someone please tell me how I can make the Selling Preferences appear?

If you haven't selected, and set up, a seller billing preference (under general preferences) it may relate to this.   ?:|
