Update: The dates of the conference are actually June 19-20. Sorry about that.
(Patrick will never let me live this down.)
My friend Patrick Masson has put together a two-day conference at Delhi, NY on May 23-24 that looks terrific. The first day, which is about open source in higher education in general, has tracks on quality, total cost of ownership, and external support. The second day is a Moodle Moot. I'll be one of the speakers.
Be there or be rectangular, as they say.
