You guys are great, all good ideas!
I have another one.
If you know anyone playing Janus or Gothic with him,
I will pledge unlimited support and analysis to any game
in progress. I think I am pretty good in Gothic, but I don't
know if I am any good in Janus yet.
Still, pass the word, discreetly, to those you can trust
who also would not mind beating him. Maybe a few stripes
in the loss column will convince him to go elsewhere.
Also, if you know any experts or top guns in other games,
see if they would be interested in taking him down.
