I've just joined a 32 team dynasty league, ( been running for ten years) and there are four more teams available if anyone is interested.
Now the teams aren't exactly good but they mostly have good cap room and if your willin to do some work then you should have a lot of fun.
Have a look at the teams with white logos they are the available ones except for the rams and dolphins.
The league is exactly like the nfl in every way cost $100 to enter and has a run down of everything On the messageboard
If anyone is interested I'll give you the commissioners email.
