# join_forge_cohort

Join the signed-in person to Pirate Forge live sessions: a whole cohort from now on (phase "all") or one phase ("build" or "grow"), by quarter key from my_forge_sessions. Only sessions still ahead are added; needs active Forge access. The answer says whether the calendar invite went out or Ben adds it by hand.
