A lot of folks don't seem to take advantage of the discounted Display Ads in the magazine for non-commercial events -- $75 for a full page in the hard cover magazine.

As mentioned the schedule is publish online Free (Google Analytics info for March:
Visits: 24,216
Unique Visitors: 10,178
Pages Viewed: 100,071)

And then goes into the magazine (2000 mailing list)

Not many seem to take advantage of that.
