Go

type List struct {
	Success  bool
}

func Home(w http.ResponseWriter, r *http.Request) error {
	if r.URL.Path != "/" {
		return PageError(w, r)
	}
	var user List
	user = List{
		Success: true,
	}
	if r.Method == "GET" {
		return HomeTmpl.Execute(w, user)
	} 
	} else if r.Method == "POST" {
		Newsletter(w, r)
		return HomeTmpl.Execute(w, user)
	}
	return nil
}

base.html

{{if.Success}}
    <li>
        <h4><a href="/signout">Sign Out</a></h4>
    </li>
{{else}}
    <li>
        <h4><a href="/login">Log In</a></h4>
    </li>
{{end}}

What I have tried:
