I know the possibility that the user can set its language by using the gear icon.
However, my concern is the following: I am interested in the initial page view. I would like to control (via the query string in the URL) which language is initially displayed, e.g.
<iframe id="ifm" src='example.site24x7signals.eu?lang=en' scrolling='yes' align='center' height='100%' width='100%' border='0' frameborder='0'></iframe>
Looking forward to your comments on this feature request.
