For example: (registration group, premium group...etc), Membership registration need activate via email. admin can add new group, edit and delete group, can edit members and change them to other group. admin cp can set premium group membership account expiry time(d/m/y), Once this premium membership account expires, It will automatically become registered users. also admin can set and edit each premium membership HDD use Capacity(GB) and Bandwidth Size(GB). Free(Visitors) and registration group, admin cp can set limit upload and download files number(pcs) in daily(24 hour).
