a newbie question

Hi... I am new to Smartlist and have a very basic and simple question to ask: I have successfully run through the Smartlist shell install file, and consequently created a mailing list "testing" under the the user name "slist", so I have a dir /home/slist. all files sitting under /home/slist/.bin and .etc There aren't any more information on the INSTALL and Manuel from here onwards. Now if someone would like to subscribe to my mailing list "testing", who should they mail to: slist-request@my.domain or testing-request@my.domain ?? Of course, I have tried these options and the mail bounced back with an user unknown message. Something is not right here and I would appreciate any help michael
