The if condition for COPPA would just be a condition based on the usergroup. By default it is usergroupid 4. So, something like:

<if condition="$userinfo['usergroupid'] == 4">
stuff only for if the user is in usergroupid 4
</if>

However, I know nothing about that mod, now what variables you need to use ($post, $userinfo, $bbuserinfo, etc) which is why if you have questions regarding a mdoification, you need to post in the modification thread for help. If what I posted doesn't help you figure it out, then that is where you need to ask for more help.
