I was just thinking, since I've missed a couple of 'prediction game' predictions (namely, the football one BigSister runs), that it would be a good idea if it were at all possible to implement a feature that reminds you to post your predictions - or indeed to post at all in some other form of game - at a set time?
I know in the example I've given that, usually, joeysteele takes it upon himself to send out reminder PMs to most players

but it'd be handy and more dependable should, for example, Joey forget or be too busy one time.
Not sure how it'd work because it would require someone making sure deadlines are set but it'd be useful I think. Off the top of my head, Calderyon and his Big Brother nominations/evictions prediction games, and the big Chat and Games "tasks" would benefit from it, too.
