hi Hans
i will try to do some logs filtered like you said , and will also try to
compress as much as i want the full ones. ( i may be able to transform 150M into
no more than 10M, its all plain text)
i will send you here and the list as soon as i do this .. dont know if ill be
able to do this today, but tomorrow you'll get the full logs even if i have to
open the ftp for you myself :- )
thanks
