The biggest frustration is signing on and not being able to play something.

Something hourly would be nice. A freeroll from 10-20 would be fine, then do a buy in for 10-20 on the halfhour.

I mentioned Seals method because it's a good way to get people playing AND paying. Win a freeroll and you can hop right into another tourney for even more. It's a nice fit. Odds are you'd be getting most of the freeroll chips right back.
