It would appear that the folk at CDNJS have suggested that their hosting of js scripts should be based on the number of github watchers. While that is clearly an unreasonable standard for end-user scripts, as long as Moodle Math types have github acounts anyway, please take a moment and help ensure that all furutre updates will remain in the cloud by clicking on the following link and clicking on the star in the upper right hand corner of the jsxgraph github project page. Thank you. https://www.github.com/jsxgraph/jsxgraph
