I tried to use Scholar. I did not break anything when, after much study, it appeared to me as a murky mess. I read the documentation, I looked at all the options and I never figured out how to achieve the results in the example shown on it's main page.
I deleted it.
I installed a new theme.
Now when I go to my primary site in a multisite install, all the stuff from Scholar is still there. Oh joy, do I care? How to make it go away? (I can't delete and re-initialize the primary site, WP says NO!)
