Mauri and All on the List,

It was not my intention to criticize Mauri, especially since he was not 
writing in his native language.  There is no doubt in my mind that Mauri's 
English is far better than my Italian.

I should have said that I really didn't understand the point which he was 
trying to make.

If I have have angered anyone, please accept my humble apology.

Best Regards to Mauri who answered my question in a private-email.
