[Mailman-Users] set the same password if a user owns several lists?

[gerard]

Hello all,

i have mailman 2.1.8. Users own several lists, and they often lost their 
password to moderate the list.
Is it possible to retrieve a form of the password of one list, to put it 
in another list? like we do with shadow passwords in unix system? i 
don't need to retrieve the password, just the encrypted form.
With python shell, i try to look at file Mailman/Cgi/options.py.
The Web interface told me that:
"Sem-edp list run by me at example.org"
but when i did:
 >>> user
'me at example.org'
 >>> mlist.isMember(user)
0
 >>> mlist.GetOwnerEmail()
'sem-edp-owner at example.org'

is it normal? I also find mlist.password thats returns something 
encrypted, is it what i need?

thanks in advance for help,
