One of weak points which plain PHP-Nuke is user manager. As an administrator, we need more flexible and functional user management options. The user manager of PHP-Nuke provides you with only three management functions: 1) modiy, 2) edit, and 3) add an user at a time.
NukeKorea Dev. Network has been trying to add more professional functionalities such as
1) Highly intergrative and easy-accessible GUIs to manage users
2) Batch pruning inactive users
3) Fully-fledged pending user management with GUIs
4) New pagination GUIs
5) delete multiples of selected users,
6) remove all users at a time,
7) more information about users, view methods, page-per views,
8) more than previous 25 options."
9) + previous features
