[Mailman-Users] How to subscribe an user without his/her confirmation?

[Simona]

Hi all,

I'm developing an unified system using PHP that I would like to use to 
manage users' subscriptions to my website, forums and newsletters.

So, I'm asking you if there is a method to subscribe an user account to 
my Mailman lists without his/her confirmation via e-mail (I need to 
manage all confirmation procedures via PHP code...).

Thanks in advance.
