On a side notes, when you browse for sprite submissions, the list will show you the submission kind for each of the sprite. Perhaps we might build a better main site software someday. Maybe around the time when the sun becomes a red giant.
I forget to mention. I have disabled the new submission upload bar because it causes more problems than improving the site.
If you are new here and trying to submit a submission, please be patient and allow the site to manually upload the files. If you are using Google Chrome, you can actually see how much the percentage your files are uploaded at the bottom left corner.
EDIT: In addition, I have also fixed the duplicate comment bug.
