Welcome to the TSN, Jack! If it feels like you just had a lot of information laid on you, don’t worry too much. Just get accustomed to the game, and we can lead you the rest of the way during the Duty Shift (what we call our Saturday meetups). Like Blaze said, showing up around 30 minutes early would be ideal so we can get you sorted out.
Also, I’d recommend subscribing to the Out of Hours Games thread. It’s not super active, but it will let you know if anyone tries to put a meetup together at other times in the week.
It’s good to have you with us. o7
