Hi sollyth,
Thanks very much for your appreciation and your post.
WPML integration is actually scheduled for the 1.8 release of the plug-in, which should be out by the end of next week.
If you desperately need this functionality now, you can download the BETA version from the following URL:
http://downloads.wordpress.org/plugin/responsive-menu.1.8.zip
Please note however that I can't be held accountable for any problems it may cause as it is still in the BETA stage.
Many thanks
Peter
