Registration Form

The site where I am using Easy Discuss is being designed for Community Engagement. I need to ensure that people who register live in the appropriate geographical area. I can do this using conditions in Breeze Forms after I substitute a custom form for the Joomla account creation form. This is because I need to collect address details and postcode/zipcode on which a test will be done to see they are eligible to join the forum. I can also include the Forum rules so that people have to agree to them.

I can't find a switch in the settings to direct Easy Discuss to use the Joomla Account Creation form which would in turn direct the user to the Breeze Custom Form.

What would you suggest is the best way of going about this concept with Easy Discuss?

Thank you,

Ric
