Custom ray visitor name

Hi, i made a little change in /ray/modules/chat/inc/actions.inc.php , in default when a visitor connect to the ray chat his/her name is Visitor but its a little annoying when there is 10 visitor with same name, so I changed the name Visitor+random number it works fine when I using it without RMS but when I turn on RMS it goes back to default and all visitors name will be Visitor. Pls help me to fix this :)

$visname = "Visitor".rand(10,99);
$aUser = array('id' => $sId, 'nick' => $visname, 'sex' => "M", 'age' => 25, 'desc' => "", 'photo' => $sManImageUrl, 'profile' => "", 'type' => CHAT_TYPE_FULL);

it is shit! 10 Users called Visitor in chatroom. how is how????

And when i rename it, or use another values link visitor #hour#second# in the english.xml they dont know what

You can only fix this problem, when you edit the flash file of the chat. but i dont have a flasheditor,
