We are customising the default fields on the WP sign up form to include;
1. Date of Birth
We'd now like to check if / how that these will then be included;
a. in the default Membership register form ?
b. as data fields to ping to other parts of our system - eg. our email provider & a separate application that we will be running that is country / age specific in how it runs (we have the API to receive this data, so just need to know that we can pass it so the application can run properly)
