So for starters, that will be the launch date of the finals of the SSSS Character Smackdown.
It will be just after the YoinkTober challenge finishes, too. We don't have a specific prompt for the 1st, but I can envision:

giving love to / posting reviews of the YoinkTober entries,

posting one you couldn't finish in time or otherwise missed,

using the finals of the character challenge as a prompt for a new work,

panel redraw,

I'm open to suggestions...
