Is it possible to do this from the Forgotpassword.aspx page?

I tried the following but it did not work. I'm not sure the username textbox in the login control has a text property. So I don;t know how to check the user name?

Any Ideas?

Sub PasswordRecovery1_VerifyingUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LoginCancelEventArgs)
        If PasswordRecovery1.UserName = "SpecificUserName" Then
            PasswordRecovery1.UserNameInstructionText = "You must enter another name."
            e.Cancel = True
        Else
            PasswordRecovery1.UserNameInstructionText = "Enter your User Name to receive your password."
        End If
    End Sub
