I kept changing it into teen (actually it's already marked as Teen in My Account) But it won't show up elsewhere. .__.;

It is Teen, it's just that rating changes often don't show up on thumbnails. Nothing seems to work reliably to make it show that change, either. :/ It should always show the accurate rating in the DD menu bar at the top of your comics page, though.

I have this problem too. My comic's rated T but it says it's rated E in the thumbnail. I'm just worried that someone young will click it and see blood all over the page :C

Ive found that changing the thumbnail will change the rating on the thumbnail. That's what has worked for me

Mushroomcomix, it used to not do that.

But now it does, and that makes me happy.

When you upload your thumbnail, I think it just adds the rating into the thumbnail as part of the image. So uploading a new thumbnail, or re-uploading the thumbnail, should fix this.
