Or distribute sheets of bar-coded sticky labels in the registration packet and let people either fill in a name and number or affix a sticker. The latter might also improve the speed at which the things went around the room and would ensure that neither email nor names could be captured by anyone other than the secretariat. But these sorts of methods are worth the trouble only if we are convinced that there is a problem. If there is not, we are wasting a tremendous amount of time discussing solutions to it. john _______________________________________________ IETF mailing list IETF@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
