Currently we’ve been doing the South Pacific Hockey League (SPHL). I haven’t run it this term because I don’t want to constantly be running it, but I have no plans of stopping it.
The forum thread for it can be found here, although you might need to scroll down as the thread didn’t start off as a serious event. We’ve currently held the Fudge Cup twice, and the announcement dispatch for the most recent one can be found here.
So far it’s been held by me and @ProfessorHenn. I was Minister of Culture during both Fudge Cups, Henn was PM during the first and Delegate during the second, so I would say it has been a Ministry of Culture project, although given how it’s been structured it’s not easy to pass on to others.
I also know @Penguin put together a fantasy football league a while back, but I haven’t been following that super closely. That’s been an independent project.
