Hide post from guests

[akee]

Hi,

I upgrade my forum to 4.0.0, and I missing 1 modification.
I used this code on vB 3.8.x

<if condition="$show['guest']">
        <if condition="$post[postcount] != 1">
        <br><br>Please login, or  <a href=register.php>register</a>
        <br><br>
        </if></if>

How can I port this code to vB 4.0.0?

Thanks
