One link for the whole roster. Everyone paints the hours they can play, booked scrims go on the same calendar, and the times your team is actually free rise to the top. Free for everyone, no account needed.
Takes about twenty seconds. No account, for you or for anyone you send it to.
Paste the 7-character code a team-mate sent you.
A planner is kept for 90 days after the last time somebody touched it. Start a new one and share the fresh link.
