Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
People on both the Semester and quarter systems have midterms over the next few weeks, which is mostly what people consider when signing up for a game.
I'd have thought the least possible number of people have midterms right now. The first term should be ending (finals), and the second term shouldn't have hit exams yet.
Unfortunately, this game just finished. You can see how it played out here
Feel free to join the next game to have sign ups though! It's hard to predict when they'll come up but I can PM you when the next one goes up if you'd like
