Add Registration Fields for Pro-Sites

Hi,

Related to this post: https://premium.wpmudev.org/forums/topic/custom-registration-fields-for-pro-sites

I tried Buddypress with only the xProfile feature, created new custom fields but those don't appear on the registration page.

I also try Register Plus Redux but had some issues: if fields are required, the registration doesn't complete.

Any other way to add cutom registration fields for Pro-Sites ?

Best regards,
Frank
