How do you add manga series info with the same titles? I think it's not uncommon. Can the form compare the authors as well instead of checking the titles only?

Also, after submitting series info and unluckily hitting series having the same title, all my typings are gone when I pressed the Back button. I need to retype everything and find out the translations again. It's pretty inconvenient.

PS. Does editting description need to be reviewed by mods?

And 2 questions about genres:
Whats the difference between, adult vs mature, ecchi and hentai?
well Hentai is easy to understand but it's just a continous variation 😛

How about a new genre for pets / animal / plants. Pets comics are pretty unique from the other genres.

Don't some people just add the author's name in parenthesis after the title if it has the same title? I'm pretty sure there's a couple of mangas here that do that.

Correct, if there are two series with the same title, just add the new series with something like this:
Series name (Author)

Editing descriptions does not need an admin's approval, but we do keep records of who changes what so that we if find something wrong, we know who to blame

Adult is more about sex
Mature is about mature topics not just including sex, such as violence
Ecchi is just the showing of skin and stuff. Think perverted but no sex
Hentai, I bet you already know

As for a new genre on plants/pets, I really doubt that will happen. It's just too rare, so there's no point.
