+=head1 NAME
+
+Bugzilla::Webservice::User - The User Account and Login API
+
+=head1 DESCRIPTION
+
+This part of the Bugzilla API allows you to create User Accounts.
+
+=head1 METHODS
+
+See L<Bugzilla::WebService> for a description of what B<STABLE>, B<UNSTABLE>,
+and B<EXPERIMENTAL> mean, and for more information about error codes.
+
+=head2 Account Creation
+
+=over
+
+=item C<offer_account_by_email> B<EXPERIMENTAL>
+
+Description: Sends an email to the user, offering to create an account.
+             The user will have to click on a URL in the email, and
+             choose their password and real name.
+             This is the recommended way to create a Bugzilla account.
+
+Params:     C<email> - The email to send the offer to.
+
+Returns:    nothing
+
+=over
+
+=item 500 (Illegal Email Address)
+
+This Bugzilla does not allow you to create accounts with the format of
+email address you specified. Account creation may be entirely disabled.
+
+=item 501 (Account Already Exists)
+
+An account with that email address already exists in Bugzilla.
+
+=back
+
+=item C<create> B<EXPERIMENTAL>
+
+Description: Creates a user account directly in Bugzilla, password and all.
+             Instead of this, you should use L</offer_account_by_email>
+             when possible, because that makes sure that the email address
+             specified can actually receive an email. This function
+             does not check that.
+
+Params:      C<email> B<Required> - The email address for the new user.
+             C<full_name> - A string, the user's full name. Will be
+                 set to empty if not specified.
+             C<password> - The password for the new user account, in
+                 plain text. It will be stripped of leading and trailing
+                 whitespace. If blank or not specified, the newly
+                 created account will exist in Bugzilla, but will not
+                 be allowed to log in using DB authentication until a
+                 password is set either by the user (through resetting
+                 their password) or by the administrator.
+
+Returns:    A hash containing one item, C<user_id>, the numeric id of
+            the user that was created.
+
+Errors:     The same as L</offer_account_by_email>. If a password
+            is specified, the function may also throw:
+
+=over
+
+=item 502 (Password Too Short)
+
+The password specified is too short. (Usually, this means the
+password is under three characters.)
+
+=item 503 (Password Too Long)
+
+The password specified is too long. (Usually, this means the
+password is over ten characters.)
