The other chapters 5 and 6 are translated on other websites and have been out for awhile.
Chapter 7 is the only new one, but does seem to have a official translation.
I would assume uploading them when you yourself have not translated them might break the ToS.?
(i know nothing about uploading rules )
So i would say it is fair to skip chapters in this case.
Hopefully we can get 5 and 6 later as this is a pretty good translation from what i can tell.
Uploading other people’s TLs are completely legal as long as the group does not explicitly ban uploads to MD, and must credit the group. Eg. I can uploade some chs of Nobunagun because the group that did it (Trilobite Scans) no longer exist, which means there’s no one to object to the upload.
Furthermore, some large groups such as LHT and UTOON/Manhwafreak do not upload here by themselves, nor do they prohibit the upload of their works here; we have people uploading those here for them, and those groups are credited under the group name slot.
So unless whoever did ch5-6 says you can’t upload it in MD, you can upload it for them, on their behalf, as long as you list their group name, and they can always request it taken down to the admins
