The mailing list for listmasters using Sympa

[address@concealed]

Hi,

I'm running (ww)sympa on a debian 3.0 system.  I'm trying to set up a system 
where  one mailing list (main_list) will e-mail users on two others 
(group_one, group_two).

It seems that one way to do this would be to use the configuration:

main_list/config

user_data_source include
include_list group_one
include_list group_two

Are the subscribers from group_one and group_two included every time an 
e-mail is sent, or just when the configuration is changed?

It seems that if I subscribe to group_one, set up 'include_list group_one', 
unsubscribe from group_one, I'm still subscribed to main_list.  This seems a 
bit odd.

Hope someone can clarify.

Mark
