That thread seemed strange to me at the time. Being an editor at K5 for ages, I'm sure he's encountered worse butchery of English on many occasions. (But it looks like he left K5 in January.) I was expecting it to be a one-off - "This is annoying me!" - post. I assumed more was going on behind the surface when it dragged on... :-(
Oh well. Life's too short to hang around places that cause one to feel annoyed. With luck, he'll be back.
Peter's a big boy. Don't feel that you helped drive him away. :-)
Cheers,
Scott.
