Ed Tufte offers a discount to his seminars for "full-time teaching faculty" (as well as full-time students).
Does "full-time teaching" exclude full-time faculty who spend part time doing research? Does advising count as teaching?
Update
I contacted the organizer and they clarified that "full-time teaching" excludes most "research" faculty; it is intended for faculty whose primary job is to teach, not research faculty who also teach.
