User:Pewterfish
From NFNC
Pewterfish is not a ref, but is a Technical Author in real life and thus somewhat attuned to typos and other mishaps of text and formatting. Rather than have him bug them to fix problems with one page or another every few minutes, the refs gave him an account and told him to get on with it.
This seems perfectly reasonable.
Pewterfish can be reached as dan {at} glasshalfempty {dot} co {dot} uk, should the need arise.
