Hi Yolanda, if you are able to volunteer and help moderate sessions, please choose the session times that you are available to moderate by going to this site and choosing the date, day and time. Otherwise you can still volunteer once the conference is in progress by also going to that site. The volunteers pageg has a lot more information on it.
