Phil, >In addition to geographic affinity groups, there might be a utility to other community groups. In particular academics. Don't know about anyone else, but it sounds like a great idea to me! We have a couple of new hubs starting up in the U.S. - actually, in the Boston area! So, you guys from MIT may be interested in that one. People are starting to form email lists for the regional groups. So, maybe you want to start one as well. https://www.ietf.org/list/nonwg.html Alia has been approving the regional ones. I am copying her to get her opinion on the affinity groups. Thanks, Nalini
