thank you for your interrest

Well I visited your registration page and I see that there is no email address field on the form.

this is a template related issue.
i've set the site to use official atomic joomla template, so you can (please) have a look again.
the registration form show the email address field and the username one seems to be ok also....

I have no idea what this happens.

If you install CB 1.7.1 over on your new site do you still get this?

If you run CB Tools?

Is it possible to uninstall my current version of CB and reinstall the new one available to professional members? Would it then work correctly?
I'm not too fussed about losing the majority of the registered users of the site as the website has changed considerably and we have changed what we offer to our users. The only people I need to be registered are members of staff and I could re-register them manually.
