By default the embed code includes the language parameter for the current working language, it is possible to change the language for lists and registration according to your needs. 

Default Browser Language

Removing the lang parameter from the URL will allow the script to then query the language of the browser and will automatically use this language, this is the same behaviour as used on my.raceresult.com

Fixed Language

You can build out a web page for each language. Here you can see the language is defined as English by setting the lang variable to en.

<div id="divRRPublish" class="RRPublish"></div>
<script type="text/javascript" src="https://my.raceresult.com/RRPublish/load.js.php?lang=en"></script>
<script type="text/javascript">
<!--
    var rrp=new RRPublish(document.getElementById("divRRPublish"), 123456, "results");
    rrp.ShowTimerLogo=true;
    rrp.ShowInfoText=false;
-->
</script>
<style>
  /* Add custom CSS here or elsewhere to change the design */
</style>

Alternatively this parameter could be passed dynamically from a query parameter, however this would require additional work to implement correctly.
