[Mailman-Developers] Questions in regard to the database operations

[Danci Emanuel]

Hi!

My name is Emanuel Danci and I am the GSoC student working on integrating the Systers` feature,
dynamic sublists - http://systers.org/systers-dev/doku.php/good_to_know?s%5B%5D=postgresql , with Mm 3.0
and I have 2 questions in regard to how the database works.

First of all, how is the aliases set populated in time?
Second of all, when a user is unsubscribed, is all the data related to him/her deleted (his/hers preferences, the info related
to the address etc) ? 
 
Thank you,
Emanuel
