Ok, here's the coding on a 2.3.0 vBulletin board when you are making the cookie/remember change using your user control panel...
(it uses 2 radio buttons for input...)

 <td bgcolor="#DDDDDD">
<font face="verdana, arial, helvetica" size="2" >
		
<input type="radio" name="cookieuser" value="yes" checked> yes
		
<input type="radio" name="cookieuser" value="no"> no
	
</font></td>

and here's the code over on vBulletin 3.0.0
(It uses a single checkbox input.....)

<label for="cb_cookieuser_navbar"> 

<input type="checkbox" name="cookieuser" 
value="1" id="cb_cookieuser_navbar" accesskey="c" 
tabindex="3" checked="checked" />

Remember username/password?</label>

Hmmm, so they are both referencing the cookieuser variable.
