First, the committee meets four times a year at a minimum. Secondly, I don't think the frequency of meetings should be taken as an indication of how serious the committee is or is not. We are very pleased to be here. I don't think you will call us again next week, but that does not cast doubt on the seriousness of your work.
The existence of the committee is assured since it has existed since 1992. All of the members keep in touch, and the committee publishes a summary of its work on the Internet. I think that if we were to meet more frequently, we would not be able to test the ideas discussed by the committee.
