...Although still requires more documentation (better than it was) etc... Calls to create and update users now provides facilities to add preferences and customfields. Removed the batch calling of the web services (not needed as all calls are via POST and not GET), code is still there but commented out. V0.1.4 was removed, too many bugs!
Previous versions using the Moodle 2.1 webservice calls are still here.
Code for the next release which is under development can be downloaded from:
