Adding this feature request as a result of direct conversation with one of our promoters.
Allow the list owner to approve or reject events submitted to the list by others (members, followers, or users) for consideration to be added to the list.
Currently, any list that allows followers or members to add events to the list can be done so without approval. However, the list owner would like to make the final decision on whether the event fits the theme.
For example, a baseball event list owner has a member who added a football event to the list by accident.
