As far as scrapping the time limit goes, I'm incredibly in favour of it.
It was incredibly frustrating when creating 60 games for my speed tournament (unawares of the limit), sending out all the pm's, then having the games vanish
Scrapping the rule would also allow me to finally -RUN- that Need for Speed Tournament, which I'd really like to do.
With the rule, speed tourneys are not possible, Without it, they'd be difficult, but plausible.
I'd also like to see a delayed start option. Or a specified start time... Ie, you can create a game, and in creation, specify "Game starts at 5:00pm, sunday" then people can join at any time leading up to there, and at that time, if full, the game will start, or it will start any time after that when it is filled..
