The league is up! Do a search for "Tom's Boring Bloodbowl League". I set the password to "mordheim". This is my first time setting up a league so I don't know if all the settings are right or whatnot. Let me know if there are any issues.
Sorry im not ignoring the league, just busy with work and tax prep. I know nothing about setting up a league so i could not say if you did it correct or not. All i know is that the blitz version adds a bunch of stuff not in the boardgame, so i'd try to avoid that.
