Hi David,

Thanks for putting this plugin together. Unfortunately, it looks like LaunchRock took down their old API platform and have not provided a documented alternative. I had a look at the calls made by the original form and used what I found to modify the JavaScript to make it work.

Are you planning on maintaining this plugin? If so, I can share my changes here. Otherwise, I was thinking about releasing my own version with some changes/improvements.

Please let me know your plans.

Cheers,
Vinny
