I would like to delete my releases of 'Killing Show' (https://www.novelupdates.com/series/killing-show/) from c4 to c34 because I will be uploading them again from scratch on a new website. And yes I know about transferring links but no that's not feasible right now (for me).
Once you upload the releases to the new website, Go here: https://www.novelupdates.com/report-problem/ and type out the name of the series, the new website, and the new TOC, and explain that you're moving sites. The mods will check the report and change the URLs for you.
we'll hide what's not accessible/dead links, while keeping the ones that can be updated visible. and continue unhiding+updating the links as they come. (though we prefer to update them in batch whenever possible) chapter listing are tied with user's reading list/bookmark, hence why we don't delete them. we also keeps dead chapters for archiving purposes
now is fine too. but send them using the link mentioned in @AliceShiki 's post, not the Add Release page.
Anytime you want. NU does not dictate what Translator does. Report the new links and the existing chapter link will be replaced with the new one.
