'Not metoo' feature

[Ben Schmidt <mail_ben_schmidt@yahoo.com.au>]

Hi!

I think I've decided now that I will be switching to mlmmj for my mailing lists. 
Not all that big or exciting, but they keep my part of the world a little smoother 
than without them, and the easier the software makes it for me to manage them, the 
better.

As I think through the things in Mailman that I used to use before deciding I'd 
like to switch, a feature I'd be interested in having is a 'not metoo' feature. 
This means when the manager sends out an email it omits the sender from the 
distribution list.

How easy would this be to add? I'd be happy to have a shot at doing it myself, 
though I'd love some pointers as to which part of the source code to look at. And 
of course, I wouldn't complain if someone else would like to do it, but obviously 
I don't expect that!

Grins,

Ben.
