Is there some way to check the validity of entries for captcha setup? This is what apparently just happened:
1. new Wagn install via cldstr
2. user entered what he thought was the correct captcha info from google. This included an entry for the "proxy" field, which ended up being "<p><span>https://www.google.com/recaptcha/api.js</span></p>" (This may or may not be exactly right; this is from the web server log)
3. user failed to log in ever again into their new Wagn instance.
we should certainly write some cucumber tests to make sure captcha is working in general. We may also want some sort of as-you-go system to detect and alert us of problems.
