Thanks for the reply.

I am still not entirely sure how to get authorized to edit the github 
repository for calculus. Perhaps I should just request access from Chris Burke?

Thanks,
Jon

 Nobody 'owns' this addon.  You can go to GitHub, check it out, and 
update it.  Make sure you update the Manifest.

Info on how to access the addons is at 
https://code.jsoftware.com/wiki/JAL/User_Guide

The Git subpage for that says that Jsoftware may need to authorize you 
to edit.  Chris Burke would be the one doing the authorizing.
