Welcome!
Welcome to Wikibooks! You do not need to log in to read or edit books at Wikibooks, but creating an account is quick, free and non-intrusive, requires no personal information, and gives you many benefits, including:
 * A username of your choice for directly attributing your contributions.
 * A personal user page, a talk page, and a watchlist to monitor pages that interest you.
 * The ability to rename pages and to customize some aspects of the Wikibooks interface.
 * People will recognize you as a member of the Wikibooks community, and you will be eligible to review pages as you gain experience.
 * Your IP address will be hidden from most users, which may give you a greater sense of security and privacy.

We hope that you choose to join our community as a Wikibookian and create an account.
