I would like to post my very own manga series titled 'GABRIEL'. Please let if I can do that and how to do it as I'm new here. The manga is written, drawn and completely mine so no need for scanlantions.

Thank you.

We don't allow self-published series to be on MangaUpdates

A just ruler amongst tyrants

you should do this stuff on maybe deviantart maybe

Batoto aspires to host self-published manga (and other comics), so you could try there.

If it is hentai, yaoi or something 18+ rated you can try e-hentai.

You can always try to bring it to a publishers or a webpublisher (if it is korean, daum or Naver would be good, if it is in Japanese then try Comico, if it's in English, sorry I forgot the name, but you can look it up)

Even after dead, we raise from the ashes for the sake of manga.

I am going to leave a few links here:

You could post it on the challenge league at naver webtoons (the english site) or tapastic. there's the new spottoon, but i'm not sure if you can post your own mangas on there. And then there's always deviantart.

I'm not so sure about how to make a manga page for it on here, but if you get picked up by one of the webtoon companies to release weekly, you'll be probably be added by an admin or something?
