Once you enroll in the course, you can continue participating in the course for at least 1 year.
During that year, there is no limit to the engagement in the Slack channel, office hours, and you get full access to the online content. You are limited, however, to two 29-minute 1-on-1-s with Morgan.
You will be sent a copy of the physical book, so that you can continue referencing the advice even after the year.
