[Fis] If always n>0 why we need log

[Pedro C. Marijuan]

Sorry Sung, you know about the rules of engagement in this list... you 
have gone to 5 msgs. And that means one and half weeks of sanction. Even 
more after having warned you privately several times.
Anyhow, tomorrow I will make public an embarrassing bureaucratic 
procedure that the list has to suffer next days.
Best wishes--Pedro
