OK - I have the new package now and will migrate it to the live site after testing. Did the 1.1.0 version have no way to make registrants into joomla users?
The feature is not available in the version 1.1.0, so if you want to add that feature, you need to modify the code of the version 1.1.0 to include that feature .
I think the easiest way is upgrade to latest version .
