I figure you remember the rules, but just to make sure, I'll clue you in on the few changes.
Your first debate cannot be a rebuttal. But, once you display your opening argument, feel free to trash what the other person said.
Debating ends the second voting begins. This season, you cannot continue debating throughout the voting period. If someone posts a last minute debate, I will hold off voting for a few hours to give the person time to respond. Generally, voting begins about 8-9 AM PST. It ends on Thursday at the same time.
Those are the key rules, but, like I said, you probably know them since you helped us come up with them.
Anyway, again, it's good to have you back.
