Hi, I have worked my way thru ASP.NET 3.5 Enterprise Application Development with Visual Studio 2008: Problem Design Solution and it was very helpful as I am designing an application in which I want users to have the ability to set the security roles themselves. However I am new to ASP.NET and find myself a little lost with being able to take this solution and overwrite the Windows login username with a user defined username. Is anyone able to assit and/or point me in the right direction. Thanks.
