I remember taking an evening graduate level course at UNF's Downtown Center around 1980. Was super convenient for those working Downtown looking to advance their professional credentials or obtain continuing education. I would suggest the depopulation of much of the Downtown workforce over the years played into the demise of this project.

From my time at UNF a few years ago I saw they listed their old campus (the current MOCA) as a current classroom location. I had a few friends in arts degrees who took classes downtown, so they do (or did when I was there ~5 years ago) still host art classes for university credit there downtown.
