Notes:
This is a very alpha version. It works and you shouldn’t have any issues with it. You’ll need to manually add the field to your wp_users table. I will fix that in a future release. The data is set via an array within an array. To add another data field, just add a second array within the first. Again, I’ll make that more user friendly in a future release.
