Hey Colin,
The specific details behind adding fields to “Organizers” are unfortunately a bit outside the scope of our support forums here, as it would require custom coding…
But we can definitely help you get started in the right direction 🙂
The first thing I could recommend is to read through a tutorial on enabling custom meta fields on taxonomies, like this tutorial → https://pippinsplugins.com/adding-custom-meta-fields-to-taxonomies/
As you can see, there’s some extensive custom coding needed to get this all working.
But once you get the basics down, retrieving data should be as simple as using functions like get_option() to call up the taxonomy meta.
I hope this helps!
Cheers,
George
