vBulletin Manual - Adding a New Moderator

To add a moderator to a calendar, you select the <Add> option in the
moderator dropdown at the far right of the calendar you are working with.

You will then be presented with the following screen:

Moderator Username - Enter the name of the moderator you are adding to this calendar. This name must match a user who is currently registered on your forum.

Can Edit Events - Allows the moderator to edit all events posted on this calendar.

Can Delete Events - Allows the moderator to delete all events posted on this calendar.

Can Move Events - Allows the moderator to move events to any other calendar that thay have Can View access to.

Can Moderate Events - Allows the moderator to approve new events through the Moderator Control Panel.

Can View IP Addresses - Allows the moderator to view the IP Address of the event poster.

Note:

If the calendar permission Can View Others' Events is disabled, the only user who can view/edit/delete an event is the user who posted it and this is assuming the user has permission to edit/delete their own events.
