10.1 Change Globally? Set Globally? What does that mean?

For some of the options given in your member options page, there is a tick-box which says "Change Globally" or "Set Globally." This means that if you change this option, you can also have the change made for all your other list subscriptions with the same address to lists on the same domain. This can be handy if, for example, you want to make sure all your passwords are the same, or you are going on vacation and want to turn off mail delivery from all the lists.
