Which template should I use to insert my code that would display ad after first message (outside first message) in the way it looks like it is another post.
I have my code ready but I cannot figure into which template I should insert it to.
Thanks Brogan but adding the ad unit code on both templates mentioned ad_message_body and ad_message_below still leaves the ad unit to remain on bottom of post 1.
It does not show between post 1 and post 2.
Ideally it should show between containers of both messages.
It turns out the ad_message_below template was included within the first message container, so the ad unit would still look like it is part of first post.
All one has to do is take it outside the list item <li> (message container). So for anyone who has a similar issue, here's the simple change
I ended up creating a new template, using @Brogan conditional statements and including it on bottom of the message template ( <xen:include template="my_custom_template" /> ).
The example above is the overall idea behind having an ad unit which is between first and second message containers.
