Hi Carl and others,
This post is a kind reminder to look into the integration with WPML (http://wpml.org). Over at the WPML forums we had a discussion on contact form integration and most folks already use Gravity by making a separate form per language. However it can be further integrated and the WPML team is very eager to work with you!
Quote from Amir: "Ideally, we'd be able to place GF forms on the translation dashboard and make them translatable like all other site contents. We're doing the same with Shopp now and it's looking great."
Hopefully you can look into it and work something out that benefits everyone!
Thanks and warmest regards,
