I miss him to. Fat Cats was my favorite board on the HUB. I believe Serf just burned out here. It isn't hard to do and I believe he is now pursuing other interests. Yes he should still be reachable and if you do contact him, tell him I have been thinking about him and I hope all is well.
I am happy to see Jimmenknee take his position as mod here for if there is anyone on the HUB that can run Fat Cats the way Serf did it is Jimmenknee. He will keep this board going and hopefully one day Serf will come back to join us again.
