How to Auto-Add Guests to Cliq?

When users register their new account on my website, I want to 1) automatically add them as a Guest to join the conversations/channels on Cliq and 2) Get them added WITHOUT requiring them to verify their email or go through any extra steps.

example: They register for my app > next page loads up Cliq and they can start contributing immediately.

How would I do #1 and #2?

Thanks!
