Monthly challenges/prompt posts?

[froodle]

With the equinox and the harvest moon coming up, and Halloween not long after, who would be interested in a monthly prompt post, to go live the day of a full moon, and basically just remind us all to look at that awesome glowing ball in the sky and write fic about werewolves, or moonrabbits, or the tides, or anything that you think of when the moon is round?

Also, less frequently, a quarterly post to mark the solstice and equinox and generate some fanworks and general excitement around that aswell?
