If you're asking for the navigation location (e.g., User CP, FAQ, Members List...) in the $navbar template look for:
Code:
<!-- nav buttons bar -->
But if you're asking to place that code inside the Quick Links drop down menu look for:
Code:
<!-- user cp tools menu -->
And change your code to:
Code:
<tr><td class="vbmenu_option"><a href="chat/flashchat.php"
target="flashchat">FlashChat</a></td></tr>
And place it in the row where you want.
