Huh? what addressbook?
++The addressbook application is part of your i2p installation. It regularly updates your hosts.txt file +from distributed sources. It keeps your hosts.txt up to date, so it automatically contains all new +eepsites announced on orion +or in the forum. +
++(To speak the truth: In its default configuration the addressbook does not poll +orion, but dev.i2p only. Subscribing to orion is an easy task, +just add http://orion.i2p/hosts.txt to your subscriptions file.) +
+If you have questions about naming in i2p, there is an excellent introduction +from duck in the forum.
+How does the addressbook work?
+The addressbook application regularly (normally once per hour) polls your subscriptions and merges their content +into your so called router addressbook (normally your plain hosts.txt). Then it merges your so called master addressbook (normally +your userhosts.txt) into the router addressbook as well. If configured the router addressbook is now written to the so published addressbook, +which is a publicly available copy of your hosts.txt somewhere in your eepsites document root. (Yes, this means that, with activated publication, +your once private keys from userhosts.txt now are publicly available for everybody.) +
