FUMBBL Finally Tackled

This is sad, but not unexpected. FUMBLL have received a (fairly reasonably phrased) cease-or-desist letter from Games Workshop. FUMBBL has been the long-running online java bloodbowl client thingy, and been the premier way to play Blood Bowl for years. In fact, even now after the release of Cyanide's game, if you don't care about any of the bells and whistles - I actually think they do add something to the experience - it does a better job of simulating the game (Including all the teams, showing the maths better, etc). Of course, that FUMBBL is such a good league system, it does beg the question why Cyanide didn't just copy it wholesale, y'know? Its timing is particularly bad for RPS forumites, as their league is just coming to the close. The question that's on everyone's lips is "why now?". As in, they've been ignoring it until now. What pushed them to make the move?
