Added HCaptcha to Sign Up

So, like most things on the internet, spam is a problem! I quickly realized that when I started getting my platform out there in the world.

I added the hCaptcha solution to my sign-up forms to deter spam accounts. Hard to know which is a real person and which is fake. This has helped a bit!

Highly recommend using hCaptcha as they are privacy-focused, unlike other captcha solutions :D
