Apologies that we didn't hold a banner contest this time, but we've been busy trying to update the rest of the site as well as implement something new, so there was no time left to organize a contest. Unfortunately, the new feature couldn't be finished on time, but we hope to have it up soon!
As I mentioned previously, our designing team is currently very busy with their own lives and we've decided to only do full layout changes for special releases such as albums. Therefore, the layout was simply updated a bit to match the new Sisters color scheme.
If the banners are still showing the Stamp! ones or if it's blank, click on the banner selector thumbnails underneath the main menu, or try clearing your cookies. The banner selector thumbnails haven't been able to be updated yet to the new ones, but they still do work if you click on them. They will be changed out soon!
