Hi

We would like for listserv to compare two or more lists and extract all
the duplicate e-mail addresses found on these lists. What I would like
to ask is can we get listserv to de-dupe across lists?

I also have another question.

When I send the following command to listserv: REVIEW LISTNAME SHORT
NOHEADER BY COUNTRY, I receive list membership numbers by country. The
question I would like to ask in relation to this is how does listserv
determine where an e-mail address has come from? Is it by the .com or
.co.uk, for example, or is it determined by gateway?

Thank you for your help.

Nevena.
