Hello From France :)
officially as someone copy here it's a comitee then the GB.
But I remember that I was surprised by opposite Ideas in publications. I think now that in fact first the publication are wrote by anonymous jw and after a member of the GB validate or not.
Another possibility is anonymous writers are pro Morris or pro Lett then when a publication must be validate these anonymous ask to his master to validate it.
It's the only way I could explain what I was feeling when I read some of this shit.
Greetings
