Keith's note: At the NASA Advisory Council Committee on Education and Public Outreach meeting on 5 March 2103 Leland Melvin, the AA for Education at NASA, correctly lamented that people at NASA were not promoting the International Space Apps Challenge (20-21 April 2013) and urged committee members to spread the word. Well ... have a look at the NASA Education website. Two weeks later and there is still no mention is made of the International Space Apps Challenge. Nor is there any mention in the 21 March edition of NASA Education Express. There is still no mention on NASA.gov's calendar.
