I'm new to being a list owner and one question I have is if I set up a 
list with TOPICs how do I use that when sending out a message.

For example my list is named ABCD with Topic 1, Topic 2 etc...

Say I want to send out a message from ABCD in reference to Topic 1 and 
only want those who have subscribed to Topic 1 to get the message not all.

I can seam to find where it tells me to only send it to those who only 
want Topic 1 in the ABCD list.

I would need to know how to do it from the web and from an email to the 
listserv.

Thanks

Derek
