CI4: email and captcha need recommendation

Email will be included in RC1 - a ported version of the CI3 lib. A more flexible one is slated for 4.1.

As for captcha - the one CI3 had was pretty easy to be broken by bots nowadays so it was ripped. I think reCaptcha is the best currently.

CI4 does have a simple honeypot built in, though, that can provide similar protection to CI3's captcha. I hope to expand it on it future releases.

Thank you for your answer. Where can I see the email library code for version 4?  maybe there is a link to github?

The CI4 GitHub has a "feature/email" branch. I'm not sure if there is anything to see there.
