Fill out the required forms as usual. Most of these forms have not changed significantly from the previous versions.
When you authorize combatants, keep the authorization sheet and have them fill out their temporary card and get the authorizing marshals to sign it. This is very similar to the past. The combatant will keep this temporary card as their proof of authorization but will no longer send in paperwork. When you file your event report, the Clerk of the Roster will be notified of new authorizees automatically and will send out their cards directly.
Important note: Photo Identification is not required unless there is a doubt about whether the participant meets the minimum age requirement for the activity.
