[Mailman-Users] email admin + / ?

[Paul Reilly]

Hi,

I've been using mailman for a while and it's great.
I have 2 questions

1) how can I auto-subscribe someone to a list, without accessing the
   web page, but by sending an email ? In majordomo this would be like
   sending an "approve" message with the users details...

2) I've mailman installed at http://lists.domain.com/
   Can I assign th root web folder to /mailman/listinfo ?
   I think thould break things. Basically I just want the public
   page showing what lists are here to come up at the
   base URL of http://lists.domain.com/


Thanks

Paul
