This is exactly the functionality I have been looking for, in a minimal implementation. I love it!

When creating a participant, why require an email, though, instead of making it optional?

I'd wager that most people will use this on mobile, and therefore share this via WhatsApp or some other IM client. Adding an email then becomes a pointless burden.

Thanks for your feedback! The email is optional when creating a participant. Try it!

Indeed, thanks. I saw that it was required on the pot creation page, and then assumed it was necessary for adding users, too.
