UNIQUE MEMBER NAMES

UNIQUE MEMBER USERNAMES

By default, usernames are unique only within an individual site. Prior to NATS version 4.0.69.1, there were two configuration settings that could affect username uniqueness.

• UNIQUE_USERNAMES Require usernames on the join form to be unique across all sites. If there is a match, the user must pick a new username.
• XSELL_UNIQUE_USERNAMES Requires cross sale usernames to be unique across all sites. If there is a match, the new xsell username is automatically renamed.

On NATS version 4.0.72 and greater, these variables have been replaced with a new variable --UNIQUE_MEMBER_NAMES-- with 9 options . The first four of these options replicate existing functionality from older versions:

• only unique within site -- this is the default setting.
• unique for joins and xsells -- this replaces selecting both UNIQUE_USERNAMES and XSELL_UNIQUE_USERNAMES
• unique for xsells -- this replaces selecting only XSELL_UNIQUE_USERNAMES
• unique for joins -- this replaces selecting only UNIQUE_USERNAMES

The second five options allow for new functionality -- letting usernames be unique across sites, but allowing exceptions if the email is also a match

• unique for xsells and unique for joins(unless emails match) -- Usernames for xsells must be unique across sites as with XSELL_UNIQUE_USERNAMES. Usernames on the join form must be unique as with UNIQUE_USERNAMES, but allowing an exception if both the username and email match the existing member.
• unique for joins (unless emails match) -- Usernames for xsells do not need to be unique across all sites. Usernames on the join form must be unique as with UNIQUE_USERNAMES, but allowing an exception if both the username and email match the existing member.
• unique for xsells(unless emails match) and unique for joins -- Usernames for xsells must be unique across sites as with XSELL_UNIQUE_USERNAMES, but allowing an exception if both the username and email match the existing member. Usernames on the join form must be unique as with UNIQUE_USERNAMES.
• unique for xsells(unless emails match) -- Usernames for xsells must be unique across sites as with XSELL_UNIQUE_USERNAMES, but allowing an exception if both the username and email match the existing member.
• unique for xsells(unless emails match) and unique for joins(unless emails match) -- Usernames for xsells must be unique across sites as with XSELL_UNIQUE_USERNAMES, but allowing an exception if both the username and email match the existing member. Usernames on the join form must be unique as with UNIQUE_USERNAMES, but allowing an exception if both the username and email match the existing member.
