There is a FBB league starting back up and so far it's murky as far as everyone returning. That's the game KoBe used for his short lived league here.
If you like fancy organizational shit, you can export if you have the game or use the league site tools to manage rosters, trade offers, etc. so it's super easy to manage your team either way. But if you are not so much and prefer very basic bare bones stuff like MSL, this probably isn't your cup of liquid. Look, Fred/Greg/whatever he's called on any given day is in the league and manages fine, and he's like old as Moses, so there's hope for anyone.
UCF is also in the league.
If interested, you'll need to sign up on the message board and post in the waiting list. Just say the CavsGM recommended you. The forums are not BS quality but it's not a league that depends on it for everything.

PS: if you know like Spanish and various Euro languages, you're even more perfect for the league cause it's quite an international affair.
