Link between newsgroup linux.debian.user and the debian user mailing list ?

Hi.

I want to know it there is any link between the linux.debian.user newsgroup 
and the debian user mailing list. It seems to be the same messages on both. 
Am I right or do some people cross post in both ?

I ask this stupid question because I discovered Debian, the usenet groups and 
this mailing list at the same time, and, because of the amount of messages, 
can I unsubscribe the list without loosing contact ?

Congratulations to all debian maintainers, developers, coordinators, etc ... 
Debian is simply the best distro I've ever seen (after testing 6 distribs, I 
switched to debian). Bravo guys !
