We have banned Jan Vigne from the forum.
I have tried, John Atkinson has tried, Ariel Bitran has tried, and members of the forum have tried to assist Jan Vigne in becoming a valuable, productive, sociable member of our community, but Jan simply could not function within the group.
Jan's contributions turned regularly to hostility. Jan's contributions worked to derail threads so that his behavior and personality became the focus of discussion. And, ultimately, we felt Jan's behavior dissuaded others from participating and prevented new members from joining.
It's always unpleasant to have to ban a member of our forum, but we feel this is the right decision and we hope it helps to make the forum a better place.
