[lucida] question about integrals

[Bruno Voisin]

Hi All,

Here is a reply sent to this list an hour ago. I was surprised not to receive it through the list, and realized it had been sent to the original poster only, not to the list.

Is it the normal behavior of this list, that when you press "Reply-To" the reply is sent to the original poster only not to the list?
