How Do You Make Postbit Plugin

[EuroPk]

Basically I'm trying to make it so this post bit plugin only shows up for certin user group IDs

<!-- PK Stats -->
<br>
<div class="smallfont" style="border: 1px solid #000000; margin-bottom: 0px;">
<div><b><font color="#FFFFFF">Total PKs</b>:<font color="#2BA8EC">$kills</font></div>
<div><b><font color="#FFFFFF">PK Points</b>:<font color="#2BA8EC">$points</font></div>
<div><font color="#FF0000"><b>Rank</b></font>:<font color="#2BA8EC">$rank</a></font></div>
**THIS IS IN PROGRESS**
</div>



If anyone could help let me know.
