Just so you know, we'll be releasing an updated CB profile plugin in a day or so along with a small modification to make to JFBConnect itself. With these 2 changes, the following will be added to CB integration:
* Addition of the Terms of Service checkbox when using "Full Joomla User" registration
* Verification that the required fields have a value when attempting to register
Thanks for your patience in the matter, and you should be all fixed up soon!
