Just another Idea.  How about a way to set up a security scheduler.  Presently I have a forum I have for complaints after an on-line event.... OK It's a On-line Race! lol...  If a driver wants to complain about an accident they have 24 hours to post a new complaint.  Then everyone else has 3 days to reply to it (but not post a new one after 24 hrs).  I would like to schedule when a role is allowed to post something and when that right is taken away.  I know it might be a pain.  It is just a time sensitive thing.  I could see using it in other areas.  Setting a forum open time and when it closes.
