can this be used with Extended Registration module...

Hi - we're using the Extended Registration Component to gather extra profile info.

This uses - and does not alter - the Joomla user tables - it just adds extra tables of its own for the extra data.

Can Joomdle still be used to integrate Joomla and Moodle using this component?

Hi.

I guess you can still use Joomdle, although there is no option for doing data mapping with that component.

You can test, and tell us if you find any problems.

Do you have a link to that component?
