User Registration Process Improvement

Hi,

I just discovered today that users cannot register directly from a sub-site, that in fact it redirects them to the parent root site for registration. This is terrible for the process flow, and confusing to the site visitor who, in this case, simply wanted to register and book her appointment.

Have we got a workaround so that the registration process for a user account can happen at the site-level, rather than the root-level?

Cheers, Lee
