Basically I want to be able to add permissions to allow an extra field to appear when creating a thread. There are lots of examples with permissions, so that's not a problem. My problem lies with adding additional fields to the create thread page. Code: controllerName: XenForo_ControllerPublic_Forum controllerAction: CreateThread viewName: XenForo_ViewPublic_Thread_Create contentTemplate: thread_create I see what's being called, but I can't figure out how to add in an additional field ... then IF the field appears and something is put into it, I don't know how to save that data. I'm looking in XenForo_ControllerPublic_Forum at actionCreateThread() and actionAddThread().
