I was saying that having an [English] prefix feels useless when the section is meant for manga translated to English. This is my reason for not adding such prefix when I made the section.
The [One-shot] prefix is necessary to differentiate whether a completely scanlated manga is a series with streak of volumes or just one chapter or volume.
Unless by asking this you're intending to upload non-English-translated series.
I'm pretty sure most know that a "scanlated" manga means it's translated and no longer "raw", just as most know that a "fansubbed" anime series means it's translated.
