If I understand you correctly, I use a single table, "users". Either MySQL or PostgreSQL (depending on the application). There is one record per user, and that record contains a serial/sequential ID, set by the system, a user ID which is varchar(8), email address which is varchar(255), username which is varchar(50) and a password which is varchar(32) and stored encrypted. There are other related tables I use to record which URLs require security and which users have access to those URLs. Paul -- Paul M.
