No, but obviously (even Viki stated it regarding the TE role for OL):
an OL Editor does the tasks of all of these roles you mentioned, though implicitly, of course. I’ve explained it clearly on other post.
It doesn’t, but that’s okay.
Well, everyone is entitled to think whatever they want.
I agree with this:
and that’s why I insist the role of subber is as important as any other: requiring time, effort and responsibility… We are asked to translate with extremely care and bring high quality subs for viewers to ensure they do not read “lousy” material before Editors can start doing their magic.
I bet you didn’t know.
Scoffing?
