Music Room 3 is an inactive group, and I didn't know if I was allowed to add those without being a member. I assumed that it was okay to make the group info myself for little secondary roles in a couple chapters, but I put no group for the Music Room 3 volumes since it was such a large chunk of the series and that should be up to the original group or a mod or something
Also a lot of people aren't aware those specials even exist, I think we should at least put the chapters + titles holders there maybe with an image directing them to Omari's sister because the average person can't even find it
Well, let's say it like this: We make a big deal out of the whole crediting process and following the scanlators rules.
The right crediting is like one of the most important things here on Batoto. "No group" should be avoided if possible.
Since chapters uploaded by contributors are available immediately, we expect them to confirm the policies of the groups before they upload and to double check what they have uploaded.
Of course everybody is only human and makes mistakes, but uploaders and contributors especially should try to put in all the relevant information to the best of their abilities.
