Need help finding this bit of template code

[HM666]

I've looked everywhere in the templates. I've used Firebug to get the code but its actually NO WHERE to be found in the templates. I need to find out how I can change a background to an input field in the Create Groups page. I need to change the keyword input field to match the rest on my site. I've attached a screen shot. Here is the code via Firebug:

<div class="blockrow">
<div class="blockrow">
<div class="blockrow">
<div class="blockrow">
<div class="blockrow">
<label for="groupkeyword">Keyword:</label>
<input id="groupkeyword" type="text" style="width:20%" value="" name="groupkeyword">
</div>
</div>
<h3 class="blocksubhead">Group Options</h3>
<div class="section">

In red is what I need to find. There is NO groupkeyword anywhere in the templates at all.

I would ask on vbulletin.com but of course vB5 is such a POS that I can no longer login at all!
