What does .HH mean in a list header?
I used the Web Interface to create a Test list.  I chose to set up an
announce only list with a bottom banner.  This is the header that was
created:

Subscription= Open,Confirm
.HH ON
Validate= Yes,Confirm
Review= Owners
Send= Editor,Confirm
Reply-To= Sender,Ignore
Sender= None
Errors-To= Owner
Auto-Delete= Yes,Full-Auto,Probe(10)
Notebook= No
Owner= [log in to unmask]
Editor= [log in to unmask]
.HH OFF

.HH ON

What I find difficult in trying learning all of the ins and outs of
LISTSERV is not knowing where to look to find certain information.  If
anyone knows of a source of basic "how to's" for LISTERV, I would much
appreciate it.
