I have had the idea to implement some sort of DM event since the start. It's not something that will come in the immediate future, though. I have other things waiting to be finished before I think about that.
I do also want to add more functionality to the staff event system to make organising DM events easier in the meantime, including teams, scoring, lives, and more. There are some improvements coming in 1.15 but not enough to allow proper creation of DM events yet. But it's on my ever-growing list.
Also why the fuck is the title /siphon...?
