Mailing list usage questions

[zithro <slack@rabbit.lu>]

Hello all,

I have two questions about the Debians ML usage.

1. when subscribing, the confirmation message says "By default, copies 
of your own submissions will be returned."
What is the meaning of "default" and "returned" here ?
I understand that I should get my own replies. But I never get them.
Should I simply add a rule to move my sent mails from "Sent" to my ML 
folder ?

2. Is there some kind of interface to manage my subscriptions ?
From what I read the (new?) system is not using "majordomo" anymore.
On majordomo you could set a few options on a web page.
Does it exist here as well ?
