Good Morning,
In case someone was having the same issue I was, building an agenda for the conference. Basically its modifying your registration and not through the conference or Zoura site itself. If you have your email and confirmation number, then go back to your completed registration and click "modify your registration", then confirm information in the first page, then the agenda (item selection) page is next, add the tracks you would like your personal agenda. Go through summary and confirm pages and click finish. Your selections will now be part of your conference. Hope this helps, have a great day.
