Hi. I don't know what the relationship is between IETF and Trello, but I discovered today that even checking out the page describing a scheduled side meeting at IETF 113 requires signing up for a Trello account (that is independent of trying to schedule one, which might be a different issue). While I understand side meetings are not official IETF activities, they are using facilities that the IETF LLC is presumably paying for in one way or another, being promoted on IETF mailing lists and to IETF participant, etc. Shouldn't they be subject to the same privacy considerations as have been repeatedly discussed on this list? john
