Login and Signup Located under main menu bar

How do I get rid of the Login and Signup fields that are in the grey bar under my main menu? I have a WishList Member Widget I want to use, …and it just looks too cluttered to use when the Login and Signup fields are also under my main menu. I still like the "search" that is in the grey area under the menu bar………can I put it somewhere else if we can hide or remove the Login/Signup?
