Just a simple template mod, in your postbit/postbit_legacy template at the end add:
HTML Code:
<if condition="$post[postid] == $GLOBALS['FIRSTPOSTID']">
your code here
</if>
Replacing your code here with what you want displayed after the first post, most liky a copy of your postbit template with some of the values filed in and the message replaced with the add code.
NTLDR that looks cool
can u also make a code which will display a google ad, while playing arcade games.
a line should appear click here to continue (which displays those ads)
and when a user clicks on those ads, ads open in a new page and game proceeds in current window
what do u think ?
