Hi Elmo,
He does not annoy me.
I find him quite a helpless person with immense insecurity.
But if he does personal attack,(because he does not understand English and mistakes an English idiom 'flying the coop' for 'coup'), I am sure you would yourself would not let him off the hook.
Yet, based on your advice, I have not gone ballistics.
If I put him on Ignore and he goes on with his personal attacks, then I would look a real idiot!
regards
