[Plugin: Subscribe / Connect / Follow Widget] Language selection for Feedburner Email Subscription p

It will be nice to have options for language selection for feedburner email subscription page.
I beleve that this option can be set by the POST variable “loc“.

This is from settings page of feedburner email subscription:
<form style="border:1px solid #ccc;padding:3px;text-align:center;" action="https://feedburner.google.com/fb/a/mailverify" method="post" target="popupwindow" onsubmit="window.open('https://feedburner.google.com/fb/a/mailverify?uri=designcap', 'popupwindow', 'scrollbars=yes,width=550,height=520');return true"><p>Enter your email address:</p><p><input type="text" style="width:140px" name="email"/></p><input type="hidden" value="designcap" name="uri"/><input type="hidden" name="loc" value="ru_RU"/><input type="submit" value="Subscribe" /><p>Delivered by <a href="https://feedburner.google.com" target="_blank">FeedBurner</a></p></form>
