help for new administrator

Hello,
I just created a list using smartlist and I would like some 
information, please, if anyone can help.
What do I tell new subscribers they should do if they want to change 
their subscription options (disable mail, receive digests, receive 
copies of their own posts...). Or how can I change those options for 
them? I see a valuable ressource for this "smartlist" group: 
membership configuration is available on a website. But my group does 
not have a website.
Sorry if this question seems very basic but I could not find this 
information in the manual or the FAQ, unless I wasn't looking in the 
right place.
Any help would be appreciated,
Pip Chodorov
