3.1. How do I change a member's password?
Use the member's personal page to change his/her password. The "Membership Management" page contains a link to that page. If you don't know the member's password, use the list's admin password. (It's also possible to use the site password, of course.)
Don't forget that members can have their password sent to them anytime they like, by clicking the appropriate button on the member options login page. There is no need for you to change their password if they forget their password.
