i saw `Permission level for different types of users:`
define('QA_PERMIT_ALL', 150);
define('QA_PERMIT_USERS', 120);
define('QA_PERMIT_CONFIRMED', 110);
define('QA_PERMIT_POINTS', 106);
define('QA_PERMIT_POINTS_CONFIRMED', 104);
define('QA_PERMIT_APPROVED', 103);
define('QA_PERMIT_APPROVED_POINTS', 102);
define('QA_PERMIT_EXPERTS', 100);
define('QA_PERMIT_EDITORS', 70);
define('QA_PERMIT_MODERATORS', 40);
define('QA_PERMIT_ADMINS', 20);
define('QA_PERMIT_SUPERS', 0);
when i do registration, it inserted `0` in `level` column in `users` table. which is conflicting the upper permission. which one is correct? or how i can manage permission for different types of users?
