After several Overwatch entries were rejected due to being submitted to the Other folder rather than the Overwatch folder, a member told me that they submitted it there because they were unable to submit to the Overwatch folder.
I did some investigating and it turns out I forgot to set the permissions so that all members could submit, not just admins. So this is completely my bad.
Any overwatch submissions that were told by me that they were rejected for going to the wrong folder, go ahead and resubmit, the Overwatch option should be open now. (Only if that was the given reason, otherwise they were rejected for content purposes)
