Can I edit or delete my translation/localization/fan art/manga after it has gone public?
The easy answer here is yes. To edit any sort of content after it has gone public, all that you need to do is submit an updated version of the contest using the same procedures that you would to update normally. You can either submit the file directly from the "Publish" section of your "My Page,"[here] or you can click the "Edit" link in the top right-hand corner of your work's description. The edited version will be made available to the public as soon as it has received the necessary approvals.
To delete your content is a bit more difficult and cannot be done entirely on your own. In order to remove your work from MANGA REBORN, please contact the site administration with your request and your reason for removing said content. The latter is optional, but if there is anything that we at MR could do to improve your experience and encourage you to keep publishing your material with us, we would very much like to hear it, so that we might improve the site for the good of all.
