i do it this way:
- first made the groups inherit each other:
pex group <groupname> parent add group <parentgroup>
example: pex group vip parent add group guest
- then i add the groups from above to the ladder:
pex rank <laddername> add group <groupname>
example: pex rank default add group guest
I repeat this until i have all groups inherit from each other and until i have all groups added to the ladder. I can now promote/demote users on the ladder:
promote user <user> and demote user <user>
This is how my (most basic) setup looks like without permissions !note that the admin rank has all perms!:
