I checked in the file language/global.php and there are no variables _ONLINE and _OFFLINE, I think these are important, the development team could put them in the next release...!!!

and _SEX is missing from profile, this field have to be added too and later plural forms.

Where occurs question such as Terms & Conditions and possible answer "I agree" - there are two translation forms, for male and female.

Also depend on the context - they're can be and 2 different translations for %s files and %s file.

If the content of the string is something like "There are %s files" - the translation is one, when the content of the string is like "%s files copied" - the translation is another.
