There are 3 ways to add members:
Manually Via This Page
Complete the form and click on the "Add" button at the bottom.
You can add extended details and sessions etc once you have added the member's basic details.
Importing Members
To import members from a CSV or Excel file, go to "Members > Bulk import" and follow the instructions.
Via the API
The API is technical and is not for everyone. If you don't know what API means, you can probably ignore this.
