Hey, I remember this
Anyway, I just tried this in my postbit_legacy template:
Code:
<if condition="$bbuserinfo[userid] == $post[userid]">
This is my post!!!
</if>
and it worked as expected, so it seems like
Code:
<if condition="is_member_of($bbuserinfo, 5,32) OR $show['moderatethread'] OR $bbuserinfo[userid] == $post[userid]">
should work for you.
(If not, this is really my last try...)
