Thanks for all the replies, much appreciated.
To answer a few questions posed.
There is no money involved. It's purely for 'fun' which it was ceasing to be.
I know that with 5 active players the league was reasonably pointless. However, I am based in the UK and I know very few people who are in to baseball. Seemed like a good idea - to play with people I knew. Even though the league was a limited size.
I am in a couple of other leagues. One is based around a website of Uk based baseball fans - www.baseballfan.co.uk
(hope you don't mind me mentioning it), it's a points based roto league with 3 divisions (i'm in division 3). The other is a H2H keeper league I joined via yahoo. It's got some weird scoring settings but looks quite interesting. It's a weekly roster which suits my lifestyle.
I sent the comissioner an email telling him that I would be leaving and asking him how he wanted me to leave the team. I have had no reply. I will update you all when I have one. Jeffrey - don't think I'll punch him just yet.
