Add Extra Lines to Registration Form

Good afternoon,

I’ve been trying to figure out exactly how to add extra fields within my Theme My Login registration form. I found this link explaining how it should be done (https://docs.thememylogin.com/article/62-adding-extra-registration-fields), but I was wondering where all of this takes place and how the code should be inserted so that it doesn’t mess with the order of the other code.

I’m running an e-commerce platform, and it would be great if users could input their current “Class Years” as they register. My apologies if this is a simple task, but just want to make sure I’m doing everything correctly.

Best,
Milton
