In the following templates: registeradult, registercoppa and modifyoptions
Remove this:

<tr>
	<td bgcolor="#13486D"><normalfont><b>Invisible Mode?</b></normalfont><br>
	<smallfont>Selecting yes allows you to surf the forums without appearing in the 'Logged In Users' list.</smallfont></td>
	<td bgcolor="#13486D"><normalfont>
		 yes
		<input type="radio" name="invisible" value="no" checked> no
	</normalfont></td>
</tr>

and then replace with:

<input type="hidden" name="invisible" value="yesORnoHERE">

Where value=yesORnoHERE is replaced by either a yes or no value depnding on what you want. This will set it to whatever you want it to and the user doesn't see the option at all. You'll also need to change it in the user options page template and and do the same thing in there (I'm not sure what the name of it is though).
