How do you figure?  We always had problems in the past with people showing up, even with lots of advanced notice...
 
Don't get me wrong - I love the idea of having a league.  I'm just not surw how successful it will be.
 
What I'd really like to see is a SMALL trial run.  Based on the success of that, we can set up a longer full blown league.
 
Just my opinion though, as I'm not running it
