I just tried to upload my project here to PMC that I have had on bukkit for years but no longer want to be in that community as often. When uploading it popped up an error that it cannot be a jar file and must be a zip, not an issue, put it in a zip and even added a readme just because. Went upload again and was told "You are not the owner of this media item." What exactly does this mean and how can I correct this?
