Add reCAPTCHA to our slack invitation page
CCExtractor is a tool to extract subtitles/closed captions from video streams. It's used by universities for research purposes, as well by regular users that want to extract captions from various formats.
We use Slack to hang out as a community. Anyone can sign up on that page (see link below). To sign up, the user enters his name and email, and and an invitation is sent by email. Lately we're getting lots of spam there - robots that enter random emails addresses for some reason. We'd like to solve this by adding reCAPTCHA to our website.
Requirements to complete this task
We expect a pull request on the plugin repository (see next link), so that we can make use of the changes. Don't put in your own API key though!
