I just looked-up Paul Hronjak's list of courses. I incorrectly concluded that he started measuring in 2001, as that is as far back as that course list goes. However, he has measured courses prior to 2001.
Should we remove the "active" restriction from the list of courses when one looks at a particular measurer? That way, one could see what the true length of experience is, and not just see what they have measured that is still an active course. It's like asking for someone's work history, but "just tell me about your current employer". Not really representative of the scope of work one has done.
