[Mailman-Users] store more data than email

[Angelo Marcos Rigo]

Hi list,

I actually need to store more data from the user than his email, 
in a way to make marketing considerations, in a sql database;
can it be done at the subscription moment ? and make any relationship
that can remove the data if the user unsubscribe? or at least, fill an
column saying the user 
has unsubscribed?
