Registration Form

Hello! Steve,
I have a couple of questions regarding the registration form.
1. I have two tables - User and Profiles
Users: (id, username, password, email,profile_id)
Profiles:(profile_id, firm_name, address, phone, etc)
2. User_table will be Users.
3. How can customize registration form to have the fields from both tables? After the user registered and validated, how can update the both tables using the collected data from table-dataface__registration.
Thanks.
