You just lurk near one of the shared computers until it becomes available, then sit down in front of it and don't leave until you are finished. *g*

And I don't get paid to type in my fic. I get paid to rot in the room uselessly, in case someone gets sick or has to leave on some official business, and then I have to go and hold the lesson for them. If there is no such case, I simply waste my time there.
