Some asked for a simple form extension. I just uploaded a beta version to the marketplace. Install it, head over to https://github.com/IamSAB/pagekit-form checkout the readme and copy its first form example to your pagekit editor on a random site to get started.
Remember to set before the SMTP mail configuration correctly. I couldn't figure out, how to get PHP Mailer working ...
Feel free to open issues or enhancements on github itself. Pull request are also welcome. Hope this extension meets your requirements.
Don't forget about Christmas and what it is about. Enjoy it.
