OK brainstorming ... here's something I've actually wanted in the past - a timer control for a board.
For example, I'd want to set a timer for posting access (not read access). I might want to allow posts only between certain hours of the day - say beginning when I get up and off when I go to bed.
Why would I use such a thing? If I have a certain hot debate going on my forum, I want to allow posts only when I (or my Mods) can monitor it and control things. When I go to bed I don't want any chance of a flame war, so I'd want it to automatically disallow posts (but allow reading) between certain hours. I want it programmed so that there is no chance of me forgetting about it.
That is my idea for today. :)
