- Make sure the person you wish to remove has no outstanding debts to anyone in the group. (If you have Simplify Debts on, they only need to have a $0 balance; if you have Simplify Debts off, they need to have all individual debts repaid.)
- Go to the group settings page. On the web, you can do this by going to your group, then clicking the settings icon at the top of the right column and choosing "Edit group settings."
- Click on the red "X" next to the person's name on the group settings screen.
And...you're done! :)
