Once you’ve completed a chore you can cross it off the schedule, like this:
By using this everyone will be able to see who has done what and it might not be necessary to print out the schedule.
Chores can be crossed off by clicking a link in the daily chore email or by going to the ‘Finish chores’ menu option under ‘Edit chores’. No login is needed to access this page so you can give everyone a link to it and they will be able to do what they need to without sharing your login details with them.
