Let's check a couple things first:
1) Make sure you've filled out all the information in the form.
2) Make sure your pop-up blockers are off. They may be affecting the Google Captcha widget.
If neither of those options fixes the problem, you can shoot us a note at firstname.lastname@example.org, and we'll get you set up with CHIVE TV. Please let us know that you're having trouble with the sign-up form so we can address the issue.
NOTE: We may ask you about your device, browser, a description of the issue (e.g., loading spinner, error message, nothing at all, etc.), screenshots, etc. to help us diagnose and fix the problem. Thanks in advance!
