I love all these marathons, especially the 24 hour

, they are great !!! I agree with Yellow Roses about JUST having buyins, but I think the cost should be a mix of buyins ranging anywhere from $2-$10.
As far as password delivery ideas, how about paying for the passwords, a flat rate for all. This extra cash could be added to the prize pool or we could come up with special prizes like bubble position, last place or most point finishes.
This may not be the best way, but it is a way.
