Mail list members will have "memberOfGroup=list@domain.ltd", so i think we don't need addition "notice-field". The point is how to show it properly.

Sorry, i don't understand what you exactly want. what do you mean 'to identify member of mail list'?

There are mail lists with many members. Identify a member only with the email-address isn't possible anytime. So an extra field would be very nice.

For adding an member you would have to fill two fields:
- email address
- notice, name or something like that

You could display it so:

test@test.com (Tester)

it would be very nice if you'll add a "notice"-field for mail list members. So it would be very easy to identify a member of a mail list.
