Update a Member's Join Date
Here’s the step-by-step process for changing a member’s joining date. Start by searching for the member that you would like to update.
Once you’ve found the member to be updated, click on the edit button.
Once you’re on the edit member screen, simply click into the Joined date box, when you do a date picker will appear that will allow you to either pick a new joining date or manually type the joining date into the box. When you’re finished simply click on the update button and the member’s new joining date will be set!
