Hey again delidream,
Just a heads up that the latest release 2.0.2 has better support for translations including a Spanish translation for all front-end text (form fields and messages).
I took a look at what’s required for compatibility with qtranslate and it appeared that making sure all text is translatable with WordPress’ special translation functions is the bulk of it.
It also mentioned adding a special JSON encoded configuration file. If enough users are interested in this integration I will see if I can also provide this file as well.
If you’d like to try out the translations, try switching the “messages” option from “Custom” to “Translations”.
Let me know if you have questions!
