For those who are seeking the postbit tweak which gives "This post is hidden" text here it is.
HTML Code:
<if condition="$show['moderated']">
<div>
<span class="highlight">
<strong>This post is hidden - really not visible to normal users!!!</strong>
</span>
</div>
</if>
The colour of the text is controlled by the Highlight Font css attribute in your style manager.
I have put it just above:
HTML Code:
<div>$post[icqicon] $post[aimicon] $post[msnicon] $post[yahooicon] $post[skypeicon]</div>
Same spot for either postbit or postbit_legacy.
If you don't know which template your forum is using, the answer is simple. If your member info is on the left (like here on vB.org) then you are running postbit_legacy. If your user data is above your posts then you are running the postbit template.
Hope this helps.
