How to add extra field in registration form?

Please tell us,

How to add extra filed in registration form and how display again?

And how to use this theme again??

Hey! Backing that request + would be nice:

1- Ability to make some registration field mandatory (such as telephone or address to reach my agent)
2- Make a registration page for each profile (Builder, Agent, Realtor, etc) with different fields

Hi,
Unfortunately, OS Property doesn't have feature to have different pages for each user type: Builders, Agents, Realtors ..etc
Thanks
