my question is can we generate learners data using moodle orange school option.
Showing my ignorance, I had to do a Google search to find out more about the Mt Orange School demo. In my defense it was released a little before I really engaged with Moodle. Please do keep this limited knowledge in mind when evaluating the following response.
The Contact page on the Mount Orange site does suggest that the "Moodle community sites" forum might be the best place to find people who know something about the Mount Orange site.
There does appear to be recent activity in that forum around the Mount Orange site.
