I will say it again: PLEASE BRING BACK THE FUNCTIONALITY TO MAKE CF7 WORK WITH WPML!!!!
Anyway, since that's not available, I followed your directions on how to create a form for each language:
Dashboard > Contact: Clicked on "add new" next to Contact Form 7 at top of page, popup appeared, I selected Spanish and clicked "add new".
I created a Spanish form, copied the shortcode generated into my Spanish contact form page.
Now, the question is: WHERE DID THAT CONTACT FORM GO??? I want to edit it and it doesn't show under Dashboard > Contact.
