<input name="command_no" type="hidden" value="122008"/>
<input name="yid" type="hidden" value="21311"/>
<input name="wid" type="hidden" value="2221"/>
<input name="cid" type="hidden" value="q"/>
<input name="uid" type="hidden" value="710"/>
<input name="username" type="hidden" value="y2k"/>
<input name="uscore" type="hidden" value="0"/>
<input name="score" type="hidden" value="0"/>
<input name="content" type="hidden" value="111"/>
<input type="hidden" name="did" value="duck"/><input type="hidden" name="from" value="0"/><input type="hidden" name="page_type" value="1"/><input type="hidden" name="uid" value="ol1302368150_205"/><input type="hidden" name="putmail" value="y2k@gmail.com"/><input type="hidden" name="street" value="0"/><input type="hidden" name="front" value="0"/><input type="hidden" name="stop" value="5"/></div>
