Post event effectiveness:
*Listen to the general feedback of your event attendees. If you hear reoccurring issues or concerns about any one person, make note to pay closer attention to them if they should attend the next year. Be sure to advise the staff to keep an eye on them.
*If any sort of situation had transpired during your event, be sure to take time to review what happened and how it was handled. If applicable, discuss possible event ban for trouble making, or highly suspect individuals.
Again, it is up to you to decide and stand by your own community standards. That being said, you must also make sure to abide all State and Federal laws.
