OP is updated. Going forward, I'm going to provisionally have three games per month - feasibly, this is more likely going to be 2, so hosts are expected to ensure that their provisional slots are flexible (i.e. if you are slotted into end of October you will want to make sure you can go start of November).
try to get sign ups going once the current game has started. If you want to give it some time that's fine, ideally we will have break periods between games, but not longer than a week or two.
