Per other posts, it's not always necessary, but often prudent, to vet changes first - e.g., by posting a comment on the profile so that all members of the Trusted List (not just the PM) will get notified of the proposed change. HOWEVER, unless the change is first approved by the active member(s) of the Trusted List (not necessarily the PM) who was/were principal contributor(s) to the existing profile (or the person making the change are themselves the principal contributor to the existing profile), (1) no one should change something substantive in a profile without providing a persuasive explanation and/or reliable sources that establish that the new info is more correct than the old info and (2) no one should change something non-substantive in a profile (e.g., formatting, style, drafting) unless (a) the change corrects a clear error or (b) the existing formatting/style is clearly non-compliant with the WT style guide and the change brings it into compliance.
