HI Lor,
THe NFL thread is a weekly pool kind of game that we all joined. Frank (weegotkidz) set it up on yahoo and we all go there and put our weekly picks (although lately I have been bad about it)
You can probably still join in (I don't know how yahoo works its) but in the first post on the thread there is a link to yahoo where you can join and then make your picks.
And then you can join in the fun!
P.S. I hope New England and Tom BRady are your faves
