@mark-robustelli In our case, we collect identification data from a member (adult participant) and then they can create their account. We also allow dependents of that participant to self-register -- they need to enter identification data about themselves, and the member, before they can create their account.
So for a member: step 1, enter name, DOB, zip code; step 2, enter username and password
And for dependent: step 1, enter name, DOB, zip code; step 2, enter member's name, DOB, zip code; step 3, enter username and password
In an Advanced Registration Form
Step 1: are you a member or dependent, then enter your information
Step 2: if you are a dependent, enter the member's information
Step 3: create your account
How do we skip Step 2 when the user is a member?
Hope that helps.
