Hi..
I would say being a "moderator" is not reliant just on the
vb default 'moderator' group, for any new usergroup you'd have to setup permissions in
VB and then PP, if you want only a privileged few of your 'registered' users to mod in PP, i would move them to a custom usergroup, refresh your groups in PP and allow this new group to have 'Mod Access'
