i checked almost all of the code of CF7 and cannot find a way to integrate with qT
CF7 can't use qT functions
and qT does not have documentation or post in its forum shredding a light into this mistery
i think the matter is within CF7...
with yoast wordpress-seo it was just a matter of adding __() around the needed output strings
maybe, maybe, there's an issue with the function load_plugin_textdomain in CF7, because it seems to me that the plugin file name and the language file prefix should match
if there are some gurus around that could take a look and help join these two *great* plugins = muchas gracias = eternal sunshine
