We created the themes as a way for us to to flesh out parts of the site with a little more focus. Some have had more time spent on them than others, as some weren't sharing their month with something huge and conflicting. In hindsight, holding Omen Islands month in August just didn't work for the things we wanted to get done. I think for this reason, we'll revisit it in the future.
We're holding 'stuff' month now because we're just about to start event season, and it's giving us a bit of a breather before we start event season up again. It's also giving us a LOT of ideas that will be popping up in future months. These monthly themes have been a new thing for us, and some have definitely been more of a hit than others - both with users and staff! I hope you'll enjoy next month's theme, we're on track for it to be a good one - and an already requested one from this exact thread.
