If you want to make a change to the sessions/meetings that you registered to attend, go to your registration confirmation e-mail and click on the “View your registration” link near the bottom. That should take you to your registration on the Cvent website, where you can select other sessions/meetings. If attending a different technical committee than one in which you’re already a member of or selected, send a short note to that committee chair saying you plan to attend so you’re not in the waiting room all day. Links to TC chair e-mails can be seen at http://dev.ncutcd.org/technical-committees/.
