not sure if i got you right but try

PHP Code:

<vb:if condition="$bbuserinfo['userid'] != 0">
YOUR CODE HERE
</vb:if> 


if you want to show something explicitly to guests/not logged in userses then

PHP Code:

<vb:if condition="$bbuserinfo['userid'] == 0">
YOUR CODE HERE
</vb:if> 


is what you want.
