Re: Serpico

    I am noting a time lag (by several hours) between the time written and
the time that messages show up on the list.  What happens when you hit the
little send button?  Does the server review them before posting?  It is 5
till 7 pm and two that I sent hours ago still haven't shown up.  Forgive me
if I'm wrong but you know what happened to Serpico.
