In order to keep your member table clean and up to date, sometimes it's helpful to scrape stale data. Whether the information is out of date, or perhaps entered incorrectly from the beginning, removing membership information is simple.
Start by navigating to your member table
Link here: https://www.joinit.org/members
Click into the membership record you are looking to remove
On the top right, click the button labeled "Delete Membership"
You will see a box on the right where you can permanently remove this membership record
NOTE: deleting a member record cannot be undone!
