Virtualmin Reseller Template ( module ? )

Hi there ! I am using Webmin + Virtualmin GPL + Usermin.
It’s long since i asked a questing on this forum giving the fact that my last questions were all in vain. Still, i’d like to ask if there is anyone who knows how to create reseller accounts/templates or what i need to create them. Is there a module that i need to load ? I searched google, didn’t find any. Please explain me how i can create a reseller acccount that can add domains + user&password . I got the point with giving the user the option of adding multiple domains but i need to create a reseller account like you can create it with cpanel, pleask or any other web hosting control panel.

this feature is in virtualmin pro, not in gpl
